I am a Navy 2M (miniture and micro soldering) technician. May I recommend to your viewers cutting, tinning and shaping all your wire ends as you did at 8:28. Also, I would prep the pots, scrape or use eraser prior to installing. Tiny shavings could flake off and cause a short in your amp. Love the flux, flux is your friend when soldering. Clean job love it. Nice work.
My previous military 2M training shows through (USN). But it is important not to over assemble a project. MIL-SPEC assembly techniques are way cool, but Leo Fender assembled amps with much less precision and I am always amazed at how well his amps survive the decades of regular use.
+Deneteus I guess technically he is correct. Why not do the best job we can do though? It does not add time or much effort at all. Like I said. I enjoyed the video and the training.
After 25 years as an electrician for a day job, I would say the 120VAC is more dangerous. It grabs you and you can get "hung up" and die. The DC tends to toss you against the wall and burn your fingers. Momma got nailed with a cap I had reformed. I am positive I discharged it, but you know how they can be. Thank God it was not at the 400 v. My other tube power supplies are X-kits, and a Jap model with Jap versions of a 6L6. Luxman used the tube. It is a great unit too! reg E&I!
I built one of these a few years ago. Great amp and fun to record with too. Not too sure what "mods" are in place from an original 5e3 but it sounds killer and very sensitive to the right hand. You can go from clean to "dirt" by playing harder. Just a fun amp and it's cool to point at it and say "I built that" and have your buddies be even more impressed.
Outstanding video. The assembly manual may be the most comprehensive manual I have ever seen produced. Not a big surprise though as Rob Hull always does outstanding work. I posted this on my facebook page. Tube Depot has been on my website for years as some folks here may already know. Great work!
I've always wanted to build an amp from a kit. Going back to the 70's when people were doing that kind of thing a lot. I've been hesitant because I thought it was too complicated. This video showed me that it is a lot of detailed work, but that the kit comes with a solid set of instructions on how to get it done. Great video. Very well done.
For a tube regulated supply it is stable as bedrock 100,000 miles from a fault zone. You need a 5R4 low loss base rectifier for them and 6 6W6GTs. I use a Chatham JAN 5R4 in mine. The warm up delay is a feature, which I have incorporated into some of my own amp designs. A 6C30D works great. They delays are work off of heat which is really handy. I got my knuckles into that horribly placed B+ term in my mom's Supro 1624T in 1980 and I was hooked! zzt! I suppose I'll post my newest junk find.
Nice work. Tidy lead dress too. Not a fan of the PCB though. I reckon the double sided boards and tracks introduce stray capacitances. I prefer thick gauge hookup wire instead.
I'm about to build my first 5F2a from scratch and have watched all of your videos. They are really well executed and very helpful. Tell Steve not to scratch his Les Paul with his car keys! ;-)
man what an inspiring video I really want to build one of these and a Marshall 18 watt .Was just starting to wonder what I would have to do to build my own amps.This stuff is fascinating to me.
Learned something very valuable watching this... tin the wires good, then use a blob of solder to fasten the wires to the tube pins. Trying to get two hands into that tiny space is nearly impossible, and extremely frustrating.
I am onto really cool old bridge that I can prototype with matching impedance ratios. I also own that Lambda in the background. I outgrew it and have 2 Gates 500 V 3A unregulated, and a 1200 V Fluke 3 A. The Lambda is on a curve tracer for matching tubes like nothing else can. You can kill yerfelf with the B+ or the 120 primary. That gives me 6 amps at 1000 volts with diodes for protection. 5E3 must be the most common kit amp. The parts are so so, but Fender bought low bid parts anyway.
I had absolutely no idea what was going on the entire time and I still watched the entire thing. I'm fascinated by your electronics ability. How long have you been tinkering with electronics and how much experience would I need to pull something like this off?
I love how he starts the video with "great project to put together in an evening and an awesome little amp" followed immediately by "remember, the voltages inside the amp will kill you! :)"
Absolutely great video, however I don't understand why you need a ground switch when you have a three prong plug. Aground switch used to be for an old-fashioned plug to cut hum.
Not a fan of the PCB or the speaker but after watching this and the 18watt & Jtm45+ videos i must say your solder joints are damn beautiful. Nice sheen to them meaning you used correct heat and speed, sometimes you see people doing these kits and most every solder joint is flat in colour caused by using incorrect heat and too much time which is bad because the joint can go cold over time. When people start these kits they really should buy a board and some turrets to practice getting their heat and soldering speed just right because if you haven't got the proper soldering skills you probably shouldn't go poking around in there trying to find a cold joint or other failure caused by faulty soldering.

I would lockwire/safety wire those 3 pots with .020" copper safety wire. Sometimes called .020" breakaway copper safety wire. Can be had at any aviation outlet. Red and black guarded switch covers have holes for that wire. One of many applications in a flight deck: A Nuclear Stores Consent switch. The weapons officer has to break the wire to lift the guard on the switch to arm nuclear stores. Special tools are not required for twisting .020" copper wire.
Hi, sorry to bother you Rob,, but with the 450V +B you get with the GZ34 and the 357V AC secondary on the large power transformer , what are those pour 6v6 idling at with the 250 ohm cathode bias resistor. The old 5e3 was using the same resistor value but with a 5y3 rectifier and 360V plate voltage, and it was allready running pretty hot.
Hmm. My bad - I honestly thought the 5E3 was a tidbit more complex than the 5F1. But in that case, I'll have to have a go at the 5E3, it's so cool. Thanks for your insight.
I see the link for the new power transformer that is included in the kit is the deluxe reverb transformer from classictone. Good move.. This one is rated at 330VAC/120mA compared to the previous one that had around 355VAC/120mA rating. The 330VAC is perfect for a 5y3 to get a cooler bias and more vintage correct PI/preamp voltages. Also include a 12ay7 instead of a 12ax7 in V1. I did calculate the idle dissipation of the 355VAC//250ohm combination and it was ~18.9 watt pr tube.. yeicksss
@TubeDepotTV Man thanks..good luck with that 35w iron.I bought one from radio shack.P O SHIT.I can solder it s just not for me..i just built my start with custom shop pick ups and us pots wuth a blender today..Just not my thing..GREAT JOB on these amps by the way..NO JUst build me an ampeg SVT for 300 and I'm ALL In!!!
@TubeDepotTV I'm afraid we're out of thermonuclear proximity fuses, but we still have hallf tin of play- doh, hot glue, a nail clipper, about six feet of bootlace and a bottle of tabasco... ;)
Notice at 9.42, speaker magically changed to a jensen Neo 12-100, (98.4db vs 94.6db for the Jensen Mod 12-50) that should bump up output.. Wow nice build. That PT looks huge.. With the supplied GZ34 rectifier what voltages are you running the jj 6v6 at ?. I understand that the jj's can take huge plate voltages and run more current than any other 6v6.. ..I see in the manual that feedback is mentioned. Are you running the amp with a NFB from output back into PI ??
hi ! why you use gromets on tubes sockets screws inside metal box ? the screws are in contact to metal box and ground on outside box , have some isolation beetwen primary ground and secundary ground? tnx you
Hot rodded Champ amps were how Mesa Boogie got started. I like the SE touch responsiveness a lot. I have a Magnatone stereo amp to fix. The echo circuit is motor boating the whole amp. It is a relaxation oscillator. I am hoping if I get rid of the idiot mods it stops. Next step is freeze spray as it only starts when the internal cab temp is over 105 degrees F. I shall be boostin' some preamp gain stages on it. After fixing a Gizmotron last night? A $2K POS! I found 5 NOS NIB & they are trash.
i'd throw out the rubber tube sockets and use some ceramic ones. some of the old amps i've rebuilt you can cut those rubber sockets and find carbon tracing burnt through them.. cost a couple bucks more but no more smoking tubes... (well unless your bias is way out....)
The lacquring og tweed has many variations. Some like to like to use Shellack 50/50 with alcahole. Others like to use Nitrocellousa lacquer (old scool). When you lacqure the cab (spray) What kind of lacquring do you use? - best from Iceland
I've always wanted to build a small amp. (I've built loudspeakers, furniture, and assembled computers.) However, I remember ordering and trying two solderers, and neither worked well enough. I then tried a third solderer and it also seemed to work poorly. Finally, I had an epiphany--I SUCK at soldering. Oh, well. XP
When I solder wire onto a speaker, I place a piece of paper under the terminals to protect the speaker should something drop off of the terminal. Better safe than sorry. Yes, it happened to me ONCE!
I was given a Washburn VGA 30. It is a transistor amp mimic the tweed I guess, it has that crunch but clean sound is ugly and flat with no tone depth. I took of the back panel and that brought out some of the 80 seventy vife (? what is that speaker called) but still. The real thing is better I suppose.
don rutter just get a tele and a simple fender amp and crank that fucker up as high as it goes. That's how the blues has always been played. This is for a hobby.

High class workmanship once again; great job. It's 11:15pm here in the UK right now and all I wanna do is get to it in the shed! Inspiring stuff.

this is sweet, I hadn't realized how much actually goes into wiring an amp....
It's a pleasure to watch you build that. You obviously take a lot of pride in your work which I can appreciate.

@TubeDepotTV Thanks Rob. Been building amps for over 15 years. Just adding my opinion based on experience. Still, as I said, nicely put together.
The red blue and Brown wire sure plays a mean pin ball!
Learned something very valuable watching this... tin the wires good, then use a blob of solder to fasten the wires to the tube pins. Trying to get two hands into that tiny space is nearly impossible, and extremely frustrating.

also, "PCB board" would be "printed circuit board board"
Indeed useful. I am thinking of a future project - but i have a some learning to do first. Thanks again. Kind regards from Stockholm,Sweden

you really enjoy to work electronics.. cool!
I wish there were "shop" classes for adults where we could go for like 2 hours once a week to learn and actually build an amp like this.
There are. Look up mojo tone.
Nice video, cool to see the hands on makings of a tube amp. Thanks

hi !
why you use gromets on tubes sockets screws inside metal box ? the screws are in contact to metal box and ground on outside box , have some isolation beetwen primary ground and secundary ground?
tnx you
You're doing a really good job.
the dude playin' the amp at the end has a sweet "Secret Service" shirt from the shop in Cincinnati.

I was just joking this video is super helpful but I don't understand how the color of the light effects the sound?
Where can I learn to build my own amp? I want to build a vibroverb clone, and I guess I could use this build as an example and compare schematics?
@TubeDepotTV what did you study to be able to do this and were should I start?
Hi great job. What's the name of that kind of pen to drill the chassis? What kind of wire do you use for connections? Thanks for the reply .
Along the line of tubes and tube amps do guys at tube depot buy old or new tubes at all?
Dear sir : Would you be kind enough to show how to build a supro thounderbolt 50 amplifier , if possible , Thanks a lot
All I have to say is WOW !!!
this is so interesting. Id love to build my own tube bass amp.
Love the video, Rob. At what temperature do you set your soldering iron ?
Only my rectifier tune and one pre amp tube glow... one of the capacitors also starts to glow when I turn it on... what did I do wrong?
What kind of solder should I use to connect the speakers? lead?
Hi Rob Hull, is it just my computer or are the links to the pdf files no longer working?
How many RMS Watts does this one have? and how much does it cost?
The lacquring og tweed has many variations. Some like to like to use Shellack 50/50 with alcahole. Others like to use Nitrocellousa lacquer (old scool). When you lacqure the cab (spray) What kind of lacquring do you use? - best from Iceland

Can you build an AC30? That'd be awesome
Sorry, I meant what type of iron?
When I solder wire onto a speaker, I place a piece of paper under the terminals to protect the speaker should something drop off of the terminal. Better safe than sorry. Yes, it happened to me ONCE!
do you have another project that has 30W, 40w or something like that?
Hi, I'm from colombia and I believe that your channel is awesome, ¡ congratulations ! I would like know where can I find this kind of kit.
Really great job man
Hi,
How much is this kit, and do you ship to Australia? Thanks!
@TubeDepotTV Thank you
On a scale of 1 - 10 how hard is this to wire?
even for a first project? or would u recommend going on somethin else b4? cheers ;)
I was given a Washburn VGA 30. It is a transistor amp mimic the tweed I guess, it has that crunch but clean sound is ugly and flat with no tone depth. I took of the back panel and that brought out some of the 80 seventy vife (? what is that speaker called) but still. The real thing is better I suppose.
Great video, great tips
The intro is like something from a public access show.
Can this kit be modded to run 6L6's ? if so how difficult would it be? thanks in advance.
Many thanks for a great video.
sir can i get this amplifier circuit board and all parts in mumbai
thanks you....i ned informations about of proyects for venezuela!!!!!!
oh yeah, and great build!
What are you using to solder with?
What is the role of the resistor at 5:38?
I want to build this kit is it hard to make it?
Great video!!! Thanks man!!!
how do i go about getting on of these to build ?
What's the cost of a kit like that?
GREAT VIDEO!
+Egar Felowpet thank you!!!
How much and where can I find this kit?
nice work!!
is this handwired? how much is the kit?
Worth every penny. This amp is a pistol.
Excellent !!!
Bravo! Master Jedi
Great video, thank you!
These go to twelve! Well, it's two louder, isn't it?
How much did this cost?
Will I sound like Muddy Waters if I build one of these? We are thinking of making a Muddy Waters tribute band.
don rutter just get a tele and a simple fender amp and crank that fucker up as high as it goes. That's how the blues has always been played. This is for a hobby.
Great. Nice video.
i live in the uk, do you have them on sale here?
We can ship these to UK
So how much..
If I order a kit, is the kit modified to the european standards? Being 230V and 50 Hz
This kit comes with a power transformer that can be wired to operate at either 117 or 230V mains
sir what is the model no of circuit board
