That's what I used to do all day long! I did start off slow, but by the time I finished working there I was up to 2 full amp chassis per day. And I LOVED it!!!
what may start off as bad soldering will quickly become extraordinary soldering with a few hours of practice. Soldering isn't difficult once you learn the correct methods and have good tools.
Don't be scared , practise on an old , broken radios , TV , etc ! It's more easy cos is not board soldering for what I hawe still no guts ! I will recomend Y to use Silver based soldering wire , (for better and cleaner contact , with less corosion ) plus if Y can find , to be filled with cleaning cemical , inside , or if can't , use a quality paste to put on contacts , soldering iron ,etc , before Y start with contacting parts ( melting down soldering wire ) ! Ask a pro for recomandation , wich power of a soldering pen is gona suite Y ! Enjoy in future projects !
i just finished building this amp 2 weeks ago and let me tell ya this head will blow your mind. And oh my god is it LOUD. I run mine without the rectifer tube and leave the 50 watt switch on the 50 Watt position. My signal chain is an MXR Carbon copy into an MXR gt-od, into a Boss turbo distortion, MXR 6 band eq, and then into a homemade volume attenuator to switch between rhythm volume and lead volume. Jumper the inputs, and tinker until you get the tone you want. You will not be disapointed!
Hey Rob, try using nut drivers instead of pliers or an adjustable wrench to tighten the nuts on the front panel switches and pots. Nut drivers fit the nuts securely, won't slip, and have a smooth surface so they won't scratch. Otherwise, very instructive video! Thanks, Greg.
@TubeDepotTV I'd be "road testing" those every moment of spare time I had! And building them, and testing them, and modifying, and enjoying the amazing tones that only a true vintage style amplifier can provide.
I love the MojoTone Amp Kits,they have the best of every thing you'll need in your dream Amp!The 1959 100 watt Plexi British Amp "TUBE" is the very best you can ever use!My 14 year old son and my and my self have been working on our second tube amp now,and the results are unreal.To even consideration to purchase such an Marshall Tube Amp would be in excess of 5 to 10 thousand dollars!I know there are critics out there that saying,OH NO!A fact though.
Tube Depot, I love your videos, everytime I see one of your videos I imidiately get the urge to build one of your kits (specially this one ) but unfortunately my financial condition don't allow me to do so. I love your channel. You Guys Rock, Sincerely; Josh
@TubeDepotTV Very true. If I was building the amp I would try and be as true as possible to the original tube compliment. KT66 tubes just have such a unique tone. Many people don't know this but the KT66 was a big part of Jimi Hendrix's sound. More bass than an EL34, more mids than a 6L6. Ton's of headroom, a good example being the Monterey Pop festival songs.
Oh hell yes! Great googalamoogala! This is the one that sounds like God shouting from the mountaintop! Many of us in the over 50 camp think of these as the "Allman Brother" Marshalls, violin-like sustain for days, killer for slide (brother Duane), goes with a Les Paul like beer goes with pizza! Who the hell needs pedals? Only 1 down side, grumpy grouches will be screaming "TURN IT DOWN" constantly.Not recommended for apartment dwellers or small beer joint gigs. A truly awe inspiring amp!
Great Video , Thanks , Most tech guys act like they are secret scientists or some shit , Luckily Guys like you show the love and know how to help others.
***** i would like to see you come out with a vintage style super lead ( hendrix style) with the 4 input jacks on the front. although this amp looks nice and im sure sounds nice that master volume instead of a 4th jack kinda blows it for me :(
+TubeDepot Great price for the your kit without breaking the bank, example I found a half for 1600 100watt, price of this kit I would have extra left over for a decent cabinet plus buy few pedals. Would you be coming out with a 100 watt kit that can switch between kt66, el34 and 6l6 tubes, resonance knob, master volume and a jose mod.
+DALE97DSM i disagree. for the price you could get a used genuine marshall. nothign against TD but if you can buy a genuine marshall combo amp for 600 to 700 ( and that is new) why spend almost a grand on the TD one? if you can get a used marshall head for 600 to 800 why get the td head kit? i always wanted one of the kits but the lack of funds and price compared to a genuine marshall just doesnt justify it.
+lordraptor11 while it is true that marshall has some excellent tube amps and amp heads in that price range, but if you want a marshall reissue of a jtm45 head it'll run you about $2000 @ guitar center and if you want a jtm 45 combo the closest thing currently offered is the blues breaker reissue (which isn't exactly the same, 2 x 12 speakers, 30 watts instead of 45, and with a tremolo ). compared to these amps you do save building a kit from tubedepot. But you have a point that alot of people figure that a DSL40C would be close enough for less money. personally I'm building the jtm45 combo.
@TubeDepotTV I think it's a little bogus that the american distributors were putting 6550 tubes into the amps just because there was a "high failure rate". But I quote Ritchie Fleigler "These things were not used to play surf music!"
Just to be safe, take a 1 watt 1K ohm resistor. Solder it to two pieces of stranded wire. One piece on each lead. One the ends of the wire put an alligator clip. Clip the resistor between a filter cap. (These are the big can caps right off the diodes or rectifier tube) Clip onto the + terminal of the first filter cap into the circuit. Then clip the other end to the ground. Always wait 3 -5 minutes after an amp is turned off to touch anything. This R jumper will bleed any stored charges. :-)
I wish you would build me a fender tonemaster, I owned one and my amp tech said that looking inside it was a work of art.... or a twin reverb without a printed circuit board, the old fashioned way, unlike the modern clones.
This is a really informative video. My only question is, since it's Tube Depot, shouldn't you have shown the tube compliment and install? Not critizing, just asking. There's a lot of good stuff in this video and worth watching again.
Designed for small apartments. Actually, you could take 2 of the power tubes out to cut it down to 100W, at least that's what Mick Ronson appears to have done.
Gee, this is right up my alley. Maybe I could even but a set of new caps for my Magnatone. I'll just click the hyperlink here on the video page... Hmm, you'd think it would be more prominent... Maybe it's on the Google+ page... Hmm, maybe they just make these great videos and never sell anything.
Your videos and amplifier builder skills are astonishing ! But could you focus just a little bit more on the wiring of the tubes and the components ? Your speak a lot about how to drill the chassis and how to put the power transformer on it (which is I think important) but we can't see a lot of how you wire the amp, which is I think fondamental in building amps ! Still, thank you for doing these vids.
Amps can do strange stuff. Even after discharging the filter caps stray voltages from other caps can recharge them to a point. It will not kill you, but it is not pleasant. The jumper I mentioned keeps bleeding current to ground and keeps the caps discharged. ALWAYS REMEMBER TO REMOVE THE JUMPER when you are done with working on the amp, & or before you turn the amp on. It usually just blows fuses, but you will feel stupid either way if you forget.
Would it possible to have a demo of the amp. I know that there's one on TH-cam but there's so much effects on it. I'd love to hear it - as the audio sample at the end of your video sound just great - and the difference when you play with the different parameters you added to the JTM45+. Anyway, thanks a lot for all your videos and for sharing your amp knowledge.
Hi guys ! Your work looks formidably neat ! On the other hand, I'm building a '59 Fender Bassman model 5F6 and was thinking about doing some modifications (I'm aware that a JTM45 and Fender bassman are quite identical in some aspects): 1- Changing to a solid state rectifier 2- Inserting an effects loop 1- If I do this, should I change some capacitors values in the rectifying section for bigger ones ?? (I mean with more capacity) 2- I've heard that this might be a waste of time in a fender bassman because the difference in tone wouldn't be that noticable... And as a valve state amp, matching the impedances would be quite troublesome and I would have to design some buffer to lower the impedances and back. Anyway, I'm an amateur on this, what would you recommend ? Thanks for your time!
A Twin Reverb with a master volume, foot switchable channel boost, and buffered effects loop is on my bucket list for DIY builds. There are some incredible tweaks and channel mods floating around online from some amazing amp builders. One day...😁
Too bad you didn't show off the solid state/tube rectifier and feedback switch you showed us, that sounds like a very usable option that makes this amp versatile for more genres of music than it would if it was just a standard JTM45. I currently play in two totally different sounding bands (Bluesy and Stoner Metal) and my little blackstar amp does ok covering the spectrum because it's basically right in the middle of the two sound types i want to emulate but it's just not perfect for either one. Now this mod you did on the JTM45 seems to be a much better fit to switch back and forth with.
I'm very interested in a low watt version with effects loop and reverb... I'd love to build one myself... but i have no experience with any of this. But i'm a tube loving fool!...
Better get that food sorted ;-) Also it's funny how it's possible to build a tube amp in your living room for fraction of the price of commercially available ones. I'm aiming to build a simple SE amp, after building one too many stompboxes. Speaker prices are killing me tough :-( I'd love to make a 2x12 or 4x12 with V30 or some other great sounding speakers, but there's no way I'm throwing away that much money ;-)
Im very interested in this amp but cannot find any videos other than this one showing the tones. The only other one has the guy running effects pedals which defeats hearing the amp
Hello, you are a master of the amps ... first of all this is a translation since I do not know English I am Spanish sorry..I have a question I want to mount a 6n2p and a pcl86 to make a 6w on a vintage radio chassis but I have a doubt about the mass ... gnd .... and the chassis..I do not know whether to make the chassis driver with gnd ... and if that is how I do it ... I connect all the points of mass to a single point ... it can be done in several ... or only the potentiometers and jacks go.
Hi, I don't know if you have answered this already, but is there a full assembly video of the amp? Would be very interesting! Anyway very nice work and sound of course!!
Excellent suggestion. The THD Hot Plate is a personal favorite, but for those on a tight budget, check out Gerald Weber's attenuator project in his first book. It'll cost around $50 to build, and gives you about -6db. You can also daisy-chain 2 of them for-12db. I forgot about this because I play a Les Paul with P-90's thru an ancient Tweed Princeton, and I can wail nicely at socially acceptable volume levels. I'm having a "DUUUHHHHH" moment right now, my bad.
Where is the master volume in the signal chain? Does it turn the guitar signal down before the tubes or the output signal down after the tubes? If you pit the MV at 10, is that the same as a non-MV setup? May buy the kit this week. Haha
Is it "hot" enough as is? Or would it make sense to maybe add a one-wire mod... maybe through a switch so it could be turned off again? Would love to get more sound bites.
I love the way this sounds cranked. Pure awesomeness. I have never built an amp before but have a little experience with working with electronics. Which build would you suggest for a beginner? Thanks!
just 1 thing my old jtm had parmeko transformer output made in leicester a very linear top quality tx.jim said they were the best but got to expensive oil cooled jobs.and the amp was biased not to blow up as they are now all makes, and the valves were better . mullard , general electric, my plexi had some kt valves from some us military stuff i had . not glass the body was metal live anode plate volts,on it still working.modern eecc83 and 12ax7 have automatic microphonics heater cathode shorting. and the gain is lower construction is cheep. but at a guitar show was given red dragon 12ax7 they were good lasted 12 monts before the ringing started.all these sovtec stuff rubish. a good old mullard or a valve from that period . mine still going strong.but im a fan of mos fet ebay china $20 including post 8 output devices 40.40 rail psu and out the preamp of jtm. wow sound is not dry, and its 350 watts. hide it in the corner of head amp.man its loud and rocks. does a jtm warrent price no, thes fets are bomb proof.nedd sone current at high power .make a hybrid see the diference. thanks guys jj
dear tube depot how much roughlly will it cost to buy and send a jtm45 head kit to scotland including taxes etc etc , ps, what a beautiful jobyou guys did on the build , sounds amazing too plz anz back , many thanks!!!
I love how he just runs his hand over the knobs and puts everything at 10.
He surfs.
That's how Randy Bachman (BTO) did it with his Sunn Model T's every gig.
Dude dimed. Every knob....love it..
My god where has this channel been all my life
And why haven’t they updated with new amp builds lately?!?!
That's what I used to do all day long! I did start off slow, but by the time I finished working there I was up to 2 full amp chassis per day. And I LOVED it!!!
really What year?

Disregard last post about finding the right kit. This it it! Awesome!
Nice video. It takes me back to the days of my youth in the 1950s when I scratch built a lot of my Ham Radio equipment. Thanks for sharing.
that amp sounds incredible
This is my kind of father and son project… Keep on rockin
I have been watching this video for the last six months and i cannot wait to gather some money to buy the kit and make the amp myself!
Hey Rob, try using nut drivers instead of pliers or an adjustable wrench to tighten the nuts on the front panel switches and pots. Nut drivers fit the nuts securely, won't slip, and have a smooth surface so they won't scratch. Otherwise, very instructive video! Thanks, Greg.
In my experience just tightening the driver by hand (without a ratchet) is also just the right amount of tight ...
Love the nuanced control adjustment . Dime It.

Very nice job guys. Im actually building an 18 watt self-biased amplifier at the moment and this is great to watch!
Rob Hull! You are the MAN!
Great to see you're back guys!
fastest amp to dial in on the planet! I love the hand swipe to max her out! lol
@TableWolfMusic I was talking about effects pedals. And I too, have a deep desire for a TubeDepot amplifier kit!
Your wiring and assembly is beautiful!
Great Video , Thanks , Most tech guys act like they are secret scientists or some shit , Luckily Guys like you show the love and know how to help others.
I wish more than anything that you guys offered a video (and kit) on installing an optional FX loop. That would be so amazing.
I always pre-solder the input sockets at the outside of the amp. After completion, remove the whole assembly and re-install in the inside
I got a used Mesa Boogie Nomad 100. The tubes are from Tube Depot! Sounds great.
This video is so satisfying!
My little children after this video began to play the game - "Who will play first? (Clap-clap-clap!!!)" =) Thank's for all videos))
This was a lot of fun to watch. I'd really like to try building a head sometime soon.
I think about a hot-rodded plexi kit all the time ...
***** i would like to see you come out with a vintage style super lead ( hendrix style) with the 4 input jacks on the front. although this amp looks nice and im sure sounds nice that master volume instead of a 4th jack kinda blows it for me :(

Very slick amp, exactly what i am looking for. To bad i don't have the space or tools to accomplish building one. Very good video.

I built These things back in the sixties, since then i´ve moved on a bit. Semiconductors will do the Job very well too
Can you do video on building a vintage AC30/6 TB complete with Vibrato and Tremolo? I'd be thrilled!!
Great video and very informative. I love the roll of the knobs at the end.
Sounds exactly like my 80’s Peavey Bandit.
I wish you would build me a fender tonemaster, I owned one and my amp tech said that looking inside it was a work of art.... or a twin reverb without a printed circuit board, the old fashioned way, unlike the modern clones.
You guys make it look so easy. Great work! I plan to get this kit at some point. My biggest fear is screwing something up though.
Great video and great sounding amp! I imagine that the voicing of the amp on the board is another project altogether.
I wish you would make some videos really showing how your kits sound.I would like to hear more before buying.Thanks
raytheprinter i can tell you right now even without using them, that these are of great performance
This is a really informative video. My only question is, since it's Tube Depot, shouldn't you have shown the tube compliment and install? Not critizing, just asking. There's a lot of good stuff in this video and worth watching again.
best video I've seen in forever!

I was wondering which ones could I use... Thanks so much!!!
Now that was very interesting, i loved the rock paper scissors at the end, LOL
Gee, this is right up my alley. Maybe I could even but a set of new caps for my Magnatone. I'll just click the hyperlink here on the video page... Hmm, you'd think it would be more prominent... Maybe it's on the Google+ page... Hmm, maybe they just make these great videos and never sell anything.
Craig Wheeler You're right, that is an issue! The links have been added into the description.
You guys should do a video showing the tones
I´m waiting exactly for that!!! Please please do it!!
Your videos and amplifier builder skills are astonishing ! But could you focus just a little bit more on the wiring of the tubes and the components ?

Fantastic sound.

jesus, this amp sounds like a beast!
A Mesa Boogie Mark Series Kit would be Great!
OCDs about some wires inside but eyeballs switch holes on the outside... why not measure the locations before inserting the other components?
Great demo !!.........Thank you guys!
You're doing an amazing work ! Thank you very much for the tutorials !

Anyway, thanks a lot for all your videos and for sharing your amp knowledge.
Hi guys ! Your work looks formidably neat !
On the other hand, I'm building a '59 Fender Bassman model 5F6 and was thinking about doing some modifications (I'm aware that a JTM45 and Fender bassman are quite identical in some aspects):
1- Changing to a solid state rectifier
2- Inserting an effects loop
1- If I do this, should I change some capacitors values in the rectifying section for bigger ones ?? (I mean with more capacity)
2- I've heard that this might be a waste of time in a fender bassman because the difference in tone wouldn't be that noticable... And as a valve state amp, matching the impedances would be quite troublesome and I would have to design some buffer to lower the impedances and back. Anyway, I'm an amateur on this, what would you recommend ?
Thanks for your time!
The solder connections to the pot. bodies look like they might be cold. You might try using paste flux if that's a problem.
I would love to learn how to build my own 2 channel, twin reverb combo amp with effects loop.
A Twin Reverb with a master volume, foot switchable channel boost, and buffered effects loop is on my bucket list for DIY builds. There are some incredible tweaks and channel mods floating around online from some amazing amp builders. One day...😁
Great vid! Very interesting. yeah, the ole western shootout scene. hahaha
can you tell me the cost of the kit? Just curious.
Thank YOU!
You guys just built and totally nailed Marshall's greatest amp (a Fender copy nonetheless)
Keep goin (y)
1:32 You're better off using a 1/2" socket extension piece to hammer those nuts in, one good hit will do it and they'll be in tighter :)
A 20 watt version would be Cool! I would like to see a half power mod for this one!
Thanks, great video!
See it only takes 15 Minutes to build one from scratch LOL
***** Unnecessary retarded remark bud.
Nice build..14:52..man you are speedy!
Too bad you didn't show off the solid state/tube rectifier and feedback switch you showed us, that sounds like a very usable option that makes this amp versatile for more genres of music than it would if it was just a standard JTM45.
I currently play in two totally different sounding bands (Bluesy and Stoner Metal) and my little blackstar amp does ok covering the spectrum because it's basically right in the middle of the two sound types i want to emulate but it's just not perfect for either one.
Now this mod you did on the JTM45 seems to be a much better fit to switch back and forth with.
I'm very interested in a low watt version with effects loop and reverb... I'd love to build one myself... but i have no experience with any of this. But i'm a tube loving fool!...
Better get that food sorted ;-)
Also it's funny how it's possible to build a tube amp in your living room for fraction of the price of commercially available ones.
I'm aiming to build a simple SE amp, after building one too many stompboxes. Speaker prices are killing me tough :-( I'd love to make a 2x12 or 4x12 with V30 or some other great sounding speakers, but there's no way I'm throwing away that much money ;-)
Let me know when you release a kit to build a 1962 Bluesbreaker amp.
Im very interested in this amp but cannot find any videos other than this one showing the tones. The only other one has the guy running effects pedals which defeats hearing the amp
full scrape,,, i like it loud,,, you had the master volume down right :)
wrong at the start with the fillament wires, chech the black and red wires twisted together
My fav:source for wires caps ect:let me know when you have 18 AWG vintage cloth waxed wires.
What fun! Thanks for sharing.
Inspiring, I wish i had the tools.
Great Video! I wish you did a more technical one though...
Hello, you are a master of the amps ... first of all this is a translation since I do not know English I am Spanish sorry..I have a question I want to mount a 6n2p and a pcl86 to make a 6w on a vintage radio chassis but I have a doubt about the mass ... gnd .... and the chassis..I do not know whether to make the chassis driver with gnd ... and if that is how I do it ... I connect all the points of mass to a single point ... it can be done in several ... or only the potentiometers and jacks go.
Amigos, esse amplificador ficou beleza. Fantástico! Rio RJ
Good job!
Cool, I'd be very interested in that amp!!
Awesome!! Am going to buy an JCM800 kit"..
Hi, I don't know if you have answered this already, but is there a full assembly video of the amp? Would be very interesting! Anyway very nice work and sound of course!!
I'm interested in the kits is this a condensed version of the video companion to the assembly instructions or the full assembly video? thanks
Excellent suggestion. The THD Hot Plate is a personal favorite, but for those on a tight budget, check out Gerald Weber's attenuator project in his first book.

Is it "hot" enough as is? Or would it make sense to maybe add a one-wire mod... maybe through a switch so it could be turned off again?
Would love to get more sound bites.
Thanks. This is some quality knowledge!
I love the way this sounds cranked. Pure awesomeness. I have never built an amp before but have a little experience with working with electronics. Which build would you suggest for a beginner? Thanks!
Nice PRS
You should try recreate the Hiwatt tone for less price.
the last part is most fun lol
just 1 thing my old jtm had parmeko transformer output made in leicester a very linear top quality tx.jim said they were the best but got to expensive oil cooled jobs.and the amp was biased not to blow up as they are now all makes, and the valves were better . mullard , general electric, my plexi had some kt valves from some us military stuff i had . not glass the body was metal live anode plate volts,on it still working.modern eecc83 and 12ax7 have automatic microphonics heater cathode shorting. and the gain is lower construction is cheep. but at a guitar show was given red dragon 12ax7 they were good lasted 12 monts before the ringing started.all these sovtec stuff rubish. a good old mullard or a valve from that period . mine still going strong.but im a fan of mos fet ebay china $20 including post 8 output devices 40.40 rail psu and out the preamp of jtm. wow sound is not dry, and its 350 watts. hide it in the corner of head amp.man its loud and rocks. does a jtm warrent price no, thes fets are bomb proof.nedd sone current at high power .make a hybrid see the diference. thanks guys jj
