Cool Phil, a couple things. The PI resistor after the 470 ohm should be 10k. Also, my guess is that the Dumble amp used 6L6 power tubes.

Re: The new dumble modded bassman build video series... begins!
So you're saying a 10k instead of the 22k listed? Will update.
I'm fine with it being 6L6, I was guessing since he usually doesn't replace but reuses those old fender iron that it was likely it was 6L6 too but the schematic I took it from I thought said EL34? Or maybe I just couldn't find a 6L6 in the KiCAD symbols? I don't recall now, I'll see if I can update that.
In talking with Jelle, I think I hve the 'bright' cap done wrong on the schematic, but I put it right on the layout with a switchable bright. I've got it as a shunt instead on the schematic so I'll fix those.

If u put your tone caps direct on the pots, u will get space for your power caps direct on the board

It's all good, I'm going to buy a custom sized chassis that will be pretty big so I have tons of room. I've got fumblefingers so I want bigger/more room

Ok question. Do these look like the right transformers for a 100w Bassman build?
https://www.cedist.com/products/transfo ... 5-v-200-ma
Or should I go for their Hammond P-T290YX found here: https://www.cedist.com/products/transfo ... nder-120-v
and for output: https://www.cedist.com/products/transfo ... ent-fender the P-T1760W?
and finally choke:

4A filament current looks a bit low to me on. Especially if you want to use EL34s instead of 6L6 you might be screwed...pompeiisneaks wrote: ↑Sun Dec 06, 2020 1:52 am Ok question. Do these look like the right transformers for a 100w Bassman build?
