It's all about being the "master of your domain" (sans Seinfeld jokes).
Those Orange Drops always look like candy to me... almost ate one once...

What's that 25W 50-ohm resistor at the bottom for? A power attenuator?

Nope, heatsink
This amp is VERY simple, its got 4 knobs (volume, treble, bass, cut), no master volume. The guy who designed it, Ken Fisher, thought that master volumes, effects loops, and other things degraded tone. Now, he is dead and his amps are going for 40K :sad1:

I've got a set of SOZO's lying around but I'm trying to build it as close to stock as possible the first time around, then after a few months, if I feel like it needs something, I'll change it.

'tis a shame other major amp builders don't follow his lead.Rouse said:

Ah yes the SOZO's... or as I call 'em, the Zep Caps ("Zoso" - Led Zeppelin IV Jimmy Page's "symbol"). Heard good things about 'em; haven't tried 'em yet. The Orange Drops are generally preferred for Fender-style amps, and IIRC Trainwrecks were based on Fender circuits. Memory's a bit fuzzy on that...

Not at all. There were 3 Trainwreck models. The Express which sounds like a hot-rodded marshall but completly unqiue and different, very high gain. The Liverpool which is the Express with EL84s. And the Rocket which is based on an AC30 and has way less gain than the other two, when cranked, it can get some great ACDC like rock tones.

And it works! Its sound amazing. Much better than any current production Vox I've played. I love it to pieces. Even when its almost fully cranked, I get still get clean notes just be picking lighter, even the clean notes feedback beautifully. I'll try and get clips up if I can get my recording computer to work again :sad1:

Could you please post a link the ampgarage topic on this build? I'd like to learn more.

I'm convinced the tone killing Master volume has kept bands coming back to venues and saved countless guitar players' lives.

a master volume done right does not kill your tone. I used a circuit that, although expensive in parts costs, worked very well at keeping the tone alive and well at lower volumes.
and who designed this non-tone suck master volume circuit you ask? Some guy named Ken Fisher.

Yep - or "PPIMV" as seen in forums. :laughing7:
For ex, the 70's Marshall MV amps used a different MV circuit.
The Fischer PPIMV sounds better than the Marshall offering, but still
doesn't beat the non-MV... cooking powert00bs is where it's at.

Well, according to Marshall history, the reason they started producing MV amps (mid 70's) is because of the ear-splitting volume
one would have to crank a non-MV Marshall to get that "Marshall tone". This feature was in high demand.
Undoubtedly a legit reason for doing so.
But in doing so, they introduced a very noticeable buzzy pre-amp distortion into the tone.
Marshall tone got noticeably thinner after that - into the 80's and beyond.
Even with the Fischer PPIMV the tone still suffers (unless you're near "10" if you will, but then you're practically
just as loud as a non-MV) - nothing beats a wide-open non-MV amp for fat, pure tone.
Cuz the secret is in the powert00bs... that's where the tone is. And if you don't push them, you're
mostly dealing with thin preamp t00b buzz.
Nowadays we're lucky to have such items as THD HotPlates and such. While not perfect, they're still
better than what the typical guitarist schmoe had at his disposal in the 70s/80s. :laughing7:
There's also a thing called "Power Scaling" which involves yet another (but far more intricate)
circuit to stick in your amp.
I always recommend a power attenuator over futzing with installing a PPIMV or the like in the amp.
Anyhoo, now the vast majority of amps available in the last 30 years has a MV - and tone worldwide
has suffered thanks to all the Bedroom Players and their demands for "quieter cranked tone" (oxymoron) over the decades. :icon_jokercolor:
