Terry, God Bless and Protect you and your family. Thank you for sharing your wisdom with us. We love all the technical details. Bless you for saving all those beautiful cabinets and chassis from the dump. Your preserving our tube amplifier history. Your educating the next-generational of DIY amp builders.
These circuits are simple but very effective to get a great tone! Both amps are fantastic! Take one of these to a gig and see what happens! People will go nuts! Thanxz
Hi Terry, great amp! I made one somewhat similar, but on the first preamp stage I used a 6av6, then a 12AX7 for the second stage and phase inverter. Very similar to a Harvard, but I used the Blackface tone stack. Then I made the bias switchable between fixed and cathode. I also made it with switchable negative feedback.
you make this look so doable, and it sounds great. ive been thinking about building an amp for years, but it always seemed so daunting. thanks for the inspiration.
Love your DIY boutique amps! When you show your schematics they would be easier to read on the video if you used a larger sized font for the parts values. That way taking a screenshot off the video would still be legible. You could also upload the schematic to Dropbox and include the shareable link to it in your description for the video - Uncle Doug has done this before.
The EmiTone Rocks!!!! Man I wish I had one EXACTLY like it! Not only does it sound better than the one you featured in this video, but it looks infinitely better!!! Don't get me wrong, I did like this design and version for the most part...a few things I would like to have seen done differently, but on the whole, a good amp. Just way lower class than the EmiTone!
Tone is warm, sounds GREAT! Haven't heard back from you for the *.jpg* of this amp. Maybe posting it hear would save you some emails. -- Where can you get the islet board from? Part # for Power Transformer please!
Wow I think this is the best sounding amp you’ve come up with. Super nice. I’ve been building and repairing tube guitar amps for 20 years and know what a good one sounds like. What brand output transformer did you use?
Yep, I'd love to see 2E26s in push-pull-manner with stabilized screen voltage! And then maybe using another phase inverter, perhaps the old-fashioned "See-Saw" derivate - like the old Valco or Supro models used to use...
I would have thought that the eyelet board was only used as a production expedient by the makers. I would think that in a tight chassis like that, just mounting the parts point to point with minimal terminal strips would be easier to fit? Eyelet board would make maybe replacing parts more convenient, but those type of caps ought to still be good when the rest of the amp is worn out in 200 years.
Nice one! Always look forward to your videos. Always informative! Have learned a much from them. I even watch the ham videos, even though I'm not a ham guy, just to pick up useful tips. A question I'd like you to address here or in a future video where appropriate: I see you used a fuse in this build, and nearly every tube amp I see uses fuses in the AC input. Is there some reason they are preferable to circuit breakers? I would think that 1) It would eliminate the need to source spares, and 2) Eliminate the issue of over-fusing and the resultant damage. Is there some difference in the way they "blow" that makes fuses preferable to circuit breakers? Thanks again for all your work producing these informative videos!
Terry I’ve watched lots of your videos and continue to enjoy them. Question; why did you not set up your tube layout so the tubes can be seen through the “window”? I think tube picture windows are so cool. Also where did you get the eyelet board??
Layout would not allow for this cabinet. With the eyelet board, tubes are on the opposite side of the controls.I purchased the board at Watts Tube Audio. They are out of business now
Bummer! I’ve looked high and low for a reasonable priced board that could have reverb and tremolo using a pair of 6V6’s or 6L6’s. Thanks again for these wonderful projects.
I got some surplus phenolic sheet used in aircraft maintenance, a stockpile of silver solder posts and made a staking tool to expand their bases. Drill holes in a piece of the sheet and stake the posts. Custom component board. Honestly I got the posts somewhere decades ago, I have no memory. But I got a drawer full.
@@jakeblues3676 Check Doug Hoffman's site for circuit boards-- Hoffmanamps.com. I had to rebuild a blackface Princeton and his eyelet board was great, inexpensive too.
I have a solid power trafo 250-0- 250 high tention. Used i ones building VOX AC 30 . I do also have an output transformer for this ( 4xEL84) with 4-8-16 Ohm tapping . Can l use these transformers for your amp ?
You are gonna trigger all the antique radio guys with your "re-purpose" there. I have accumulated all the parts and vintage tubes to build a Champ clone amp from scratch. But I am busy restoring a Drake transmitter that I helped build, new. Noticed the tee shirt. Transformers were not so expensive. I got them from Triode Electronics instead of expensive vintage ones or boutique ones. Probably will get a Weber speaker or use a vintage speaker I have setting around. Whenever the project ever starts.
Its your fault....... you have got my "idea generation" juices flowing. I have an old radio that ran on 12v that I have stripped out. It has 2no 2W x 8 ohme speakers and 2no 4W x 8 ohme speakers. Is this suitable for a "new future" as a acoustic guitar amp with 12v or 240v?
@@d-labelectronics non that I could hear but it doesn't answer my question as I've seen it discussed by other people in forums and on other channels such as Mr. Carlson's.
How about doing a small tube amp for mp3 players, flat screen tv, & cell phones. Something in the 10 to 40 watt range. Love all your videos but like the build from scratch ones best. Keep up the good work.
Keep on doing it mate! That's what you're good at and someday I'll build my own amp thanks to you. Tony, what does It sound like cranked? If I'd lived nearby you I'd be pestering you for sure! Cheers from sweden!
Nothing better than a classic low powered 6V6 cranked.

отличный усилитель! спасибо вам за видео!
That RCA is one sexy amp, Love it, Both amps sound great, Top notch work Terry and Emi !!
"Some assembly juice required". Great amp Terry!
The "Emi-Tone" and the "RCA" sound fantastic! Thanks to Tony and Terry - good stuff!
That's a rocking
boutique refurb Terry. Cool way cool 😎
These circuits are simple but very effective to get a great tone! Both amps are fantastic! Take one of these to a gig and see what happens! People will go nuts! Thanxz
I hope that the younger generation can appreciate this.
You might do a project on your next repurpose, a combination radio/guitar amp in one cabinet. Just flip a switch from guitar mode to radio mode.
Hi Terry, great amp! I made one somewhat similar, but on the first preamp stage I used a 6av6, then a 12AX7 for the second stage and phase inverter. Very similar to a Harvard, but I used the Blackface tone stack. Then I made the bias switchable between fixed and cathode. I also made it with switchable negative feedback.
Tony is happy, then I'm happy!
Man o man! They are both sweet builds. Good show D-Lab!
Hello Frend. Very good sound. Thank you. 👍👍
My dad has that same large radio that is over Tony's right shoulder.
sounds sweet
These are my favorite kinda projects. 👍
Neat straight forward craftsmanship there Terry. Looks great and works even better. The Emitone is awesome in it's own with a rich tone reproduction!🍷
Terry , You make this SO EASSSSSY!!!
That is soo cool Terry. Love watching your videos
Very cool Terry!!
Thanks for another great video Terry!
Cheers
This is wonderful Terry. You make it look easy ; I know it's only because of your years of experience. Thanks so much.
Hey Emi’s grandpa abused that geetar too. 😉Let’s get her some lessons so Terry can keep up the killer builds? She’ll be a great player!
That was excellent Terry! That amp sounds beautiful. Very clean, crisp tone ... and that cabinet!! Damn! Your Uncle killed it! Great job!
Such a great video, so much fun.
Wonderful job Terry. Thanks for this video.
you make this look so doable, and it sounds great. ive been thinking about building an amp for years, but it always seemed so daunting. thanks for the inspiration.
Man, you’ve been cranking em’ out lately Terry! Beautiful work. Absolutely awesome.
Nice Zenith radio.

Beautiful..
Great Job! 👍

Nice amp Terry 👍
nice that is my next amp build using 6v6s
Sounds good
Sounding good Tony.
A thing of beauty and a joy to behold! That reminds me, I need to find a nice gal that will help me sodher...
Great video! Great content! ;)
Well done brother... sounds really good !!!
Wow I think this is the best sounding amp you’ve come up with. Super nice. I’ve been building and repairing tube guitar amps for 20 years and know what a good one sounds like.
What brand output transformer did you use?
I'd love to see one that uses 42's, 807 outputs 832's etc. The oddball tubes that are pretty cheap.
Yep, I'd love to see 2E26s in push-pull-manner with stabilized screen voltage!
And then maybe using another phase inverter, perhaps the old-fashioned "See-Saw" derivate - like the old Valco or Supro models used to use...

I suggest a piece of frosted glass between the light bulb and the glass panel.

nice. I have an old cabinet that has 4x16" space could that be configured to fit in that size area?

Outstanding!!
How hard would it be to add an effects loop, that amp would sound killer with a big lush reverb
Couple of shorting jacks to break in between the preamp and the output probably, is all. Maybe a cap or two for DC isolation.
Will we be seeing this on Reverb? SWEET AMP.
It was on, sold overnight
D-lab Electronics Bummer........for me. Happy it sold for you.....
"Didn't want to bore you guys watching me drill holes". Pun intended? I can only hope.
bohr' is the german slang word for drilling. So if you say you don't wan't to bore me: you did with the chassis. Stay well, Terry and all the family.

Hey man love it!! Do a 12 watt TRAIN WREAK!! I,d appreciate if youl'd explain the tone stack in detail.
I have a solid power trafo 250-0- 250 high tention. Used i ones building VOX AC 30 . I do also have an output transformer for this ( 4xEL84) with 4-8-16 Ohm tapping . Can l use these transformers for your amp ?
Everytime a vlog comes out,I immediarely "LIKE"
Thanks,Terry! Da DAA Da DAT!
How do we find these on Reverb.com?
How about a STEALTH amp?
Great! Do you sell a kit for this project?
It'd look a little cooler if he could source some of the deep-chassis switches & jacks. Wouldn't have to have the oversize holes in the cabinet.
Could you give us an idea of the costs to build one of these, ie the sum of all the parts?
My estimate $300
Has any-one done any studio recordings with a D-lab creation?

Shouldn’t the transformers be at 90* from each other??
Nope, they are shielded

The 8 ohm SPEAKERS don't care what voltage the amplifier circuit operates on!!
Terry, do you think the rectification would make a difference in tone? Ie the diodes vs tube?
Yes, a 5Y3 would be perfect for this amp. On this design I did not have the room or 5vac winding
Is there a reason you don't turn your audio output transformer so the laminations are 90 degrees to the power transformer?
Did you detect interaction in the demo?
@@d-labelectronics non that I could hear but it doesn't answer my question as I've seen it discussed by other people in forums and on other channels such as Mr. Carlson's.
The transformers are shielded. The old hocus pocus of 90 deg came from open paper bobbin designs. Does not matter now
...for the HELL of it(?)
Good times brother, Enjoyed the riff. The SolderQuest channel is taking shape. Doing a bench build series now Missing you and glad your safe !
Wouldn't all amps, especially tube amps, benefit from some sort of cooling system (a fan, or liquid cooling, heat sinks etc.)? 🎶🎸
Crank it into overdrive

dlab is the shit
You've done this before
Yep and will again, Im sure
...what are you gonna do about it?!
Keep on doing it mate! That's what you're good at and someday I'll build my own amp thanks to you. Tony, what does It sound like cranked?
If I'd lived nearby you I'd be pestering you for sure!
Cheers from sweden!
Terry, ya gotta stop mounting power / output transformers in the same orientation... magnetic coupling is a thing. It seriously offends my OCD.
...I think Terry knows what he's doing-!!!
Great work. Thanks.
