I'm always more embarrassed to post in this thread than any other :P But this was a build I've been working on for an embarrassingly long time. It's a Marshall 1974X that I got as basically a kit without instructions. I bought the cabinet, chassis, transformers, and pre-assembled board from a guy on eBay, but he didn't have a layout for wiring so I looked at a bunch of schematics and layouts and figured it out all by myself ;D Unfortunately pre-assembled doesn't mean it's guaranteed to work right. But it fired up first try, and I was so excited at how good it sounded I didn't notice that my EL84's were red-plating until it was too late and one of them committed suicide. So I retraced it against the schematic and found that whoever built it made a couple boo-boos, and eventually got around to fixing it so we're at tube-friendly currents. And yes, I put the Marshall logo on there for the sake of my vanity  ::)









I know the lead dress is terrible, I'm trying to get better :-[ The thing still runs pretty quiet though 8)

I bought a Hammond L102 organ with a frozen tonewheel assembly a few years ago for $10. Repurposed the power amp and one of the Rola/Celestion speakers into a Matchless Spitfire clone. Reused the speaker grille cloth, too. Cabinet is made of pine and control cutout is made of popular, both from Lowes.

OK, so we'll say no more about the lead dress (who am I to judge?), but this is a very nice build, Nathan.  :icon_cool:

Oh-oh, the competition for the smallest standalone guitar tube amp now becomes harder... I can't resist to post again the pics of my Radio-Tone  :icon_mrgreen: !









@thomasha : What model of Jensen speaker did you use in your small Meter Amp ? Is it the new 6.5" AlNiCo P6V ?

A+!

Yep, it's the 6.5 Jensen P6V.

I wanted to go small, but still use a guitar speaker. The box could be smaller, but wouldn't fit the meter.

So far had no success in finding a smaller speaker that would sound good with tube amp crunch distortion.

OK, thanks thomasha.

Reading you, I think that I will use a P6V or C6V on my next (a bit less) compact release.

On my Radio-Tone, I used a 60s 5" or  5" 1/2 NOS AlNiCo automotive speaker from OakTron.

Here is the tone, using a Squier Std Strat and a touch of EH Cathedral reverb :

Somehow forgot my latest creation: a Transmission Line loaded active boom box style portable speaker:
(...)
 I used a PAM8610-based digital amp board, hacked it up a bit (flimsy jacks taken off board; added a battery cage etc) and made a flanged enclosure out of some sheet aluminum I had laying about.

Do you happen to have the plans for this cabinet? Also, how's the battery life with a 9v? I got a couple PAM8610's, thinking of making a powered cabinet for my Vox Amplug 2 AC30 using one of them, and something like your transmission line project might save me the need of using huge speakers for good bass response.

Hi,
finished a small lunch box amp with the ECL86. Circuit is really simple, only one volume pot, working also as ON switch.

Outside the chassis>



and with everything inside>



This time with a proper PT!
Hope you like it!

Fine thomasha  ! Funny and clever idea... Looks like if it was the Tin Metal version of my Radio-Tone (which also uses an ECL86/6GW8).

What are the dimensions of that metal box ?
Which speaker did you use ?
Is it possible to have a picture of the open box, just to see how you managed to enter all the stuff inside ?

Thanks !

A+!

Sure ! I was in the same color scheme some times ago too :



@diydave : did you use "Ivory White" and "Surf Green" Tolex or other references ? Where did you bought them ?
