    Amp Build with Clip: JCM800 Atomica/Jose Mod

    You can get parts from any electronics supplier. I don't know of any kits available because there's more to the mod than just a switch. You have to make a bunch of changes to the circuit to get a real winner, but here's the most basic way of doing it with a pre-tone stack master volume (placed...

    Thanks :) Yep, PRP + RN65/70 + Beyschlag.

    Amp Build with Clip: JCM800 Atomica/Jose Mod

    Yep. It clean up in two different ways. There's a switch on the back to take the diodes out of the circuit. Or you can just roll your guitar volume down and the diodes won't clip at all once the signal gets below their clamping threshold.

    Can you ever dial in too many mids?

    In a traditional TMB tone stack, the EQ curve is actually scooped when you have Bass/Mid/Treble all at 12:00. You need to have the mids MAXED in order to get a flat EQ. Or... reduce treble and bass with mids at 12:00. Basically, what that means is you actually need to run the mids pushed higher...

    Amp Build with Clip: JCM800 Atomica/Jose Mod

    Thanks for having a listen. :) Which "run of the mill Marshall" should I check out? When you get down to it, this is very close to a stock Marshall circuit. So that's not surprising ;)

    Amp Build with Clip: JCM800 Atomica/Jose Mod

    I recently finished this build. "Atomica" style Jose mod. But maybe a little more aggressive/modern. I have a 6-position rotary for different clipping options on the back. Though I find myself using 2N5401s most of the time.

    Amp Build: Ceriatone Kraken 50

    Last clip. Amp is pretty much finalized.

    Some cleans-ish

    Amp Build: Ceriatone Kraken 50

    Here's a clip. This is with a 10K dropping resistor. Probably my favorite value so far. The volume is as loud as I can get it without clipping the mic on my laptop, sorry lol. I'm working to upload the other clips with different voltages too. But it takes a long time for YT to process 'em. I'm...

    Amp Build: Ceriatone Kraken 50

    All done! Just doing some testing now. I'm using a 47K 5W pot wired as a variable dropping resistor. This way, I just clip it to the filter cap and I can tune all the voltages in the amp. Typical value is 10K. I set it to 18K, which is what the Yeti uses (higher voltages). And my B+ is a...

    Preamp tubes all done. In the home stretch now.

    Amp Build: Ceriatone Kraken 50

    A bit more today. Having routed a bunch of stuff now, I'm making some notes about how to do it better the next time around. And by better, I mean more OCD lol.

    Amp Build: Ceriatone Kraken 50

    More progress today. Finished up the power section and did the power tube sockets, bias test points, impedance switch, and a few other things here and there.

    Amp Build: Ceriatone Kraken 50

    It's time for everybody's favorite part of building an amp—heaters! JK, it's the worst. Decided to run DC on V1 and V2; regular AC on V3-V6.

    Amp Build: Ceriatone Kraken 50

    More progress. I discovered I'm missing the V1a plate resistor! The value is pretty obscure and I could only find it in a different brand. My OCD alarm is gonna go off because it won't match the others lol.
