I can't find the wire from the volume pot wiper to the next gain stage. Hard to see...
EDIT: I see it now...

Re: New express build works, but volume pot doesnt
Is the circuit ground connected to the volume/tone pots?

Re: How hot does your 1k 25 watt resistor get?
Why not get a few turrests? Or, at least... Get some #4 brass bolts and nuts, maybe 3/8" long to use as turrets. Put the bolts up through from the bottom, nut from the top and use the threaded part that comes through to wrap leads around. The brass will solder nicely. Or a few brass eyelets from a f...

Re: Interesting interaction : OT primaries and heater wires
What circuit exactly is used to create the 25V DC?

Re: Interesting interaction : OT primaries and heater wires
Is your filament winding ground-referenced by a low-resistance pot? What is the resistance of your hum-balance pot? The only way I can see this being an issue is if the filament winding is weakly ground referenced such that the OT primary lines can yank the whole winding up and down. In other words,...

Re: Trainwreck transformers specs
You could try asking heyboer. They're pretty open about stuff. Just ask them core size, wire size and number of turns. They might not want to tell you the interleave, but you can ask. The worst that can happen is they don't respond...

Re: Who can supply me a head cab ?
Michael Gaines. You'll need to give him the exact dimensions needed and ask him to hunt down the wood.

Re: PT wiring question (SOLVED!!)
Very likely tie the white-stripe to the black then use the black-stripe and white as the 24VAC inputs. That would be the only logical choice given this color scheme.

Re: Transformer Questions
Why not use the standard iron from toneslut. I have some extras, too.

Re: Need schooling on the fix that corrected my issue
So... Why is there 2 ohms between the PI ground point and other ground points? Something is fishy (still needing fixed).

Re: Express Input Jack Grounding
I'm not a fan of this grounding scheme. Washers and nuts can loosen over time, get dirty then you have a bad ground. I once sent an amp across the USA, New Jersey to Califirnia. When it got there is had a nasty buzz. I had to have the customer return it at my expense. When it got here the footswitc...

Re: New to the board---and I have a few questions!
8x17x3 will work great. I use 18ga stranded teflon wire but use what ever you like. It's your amp. Teflon won't melt or burn so is far easier to use. IMHO. This is a very gigable amp but is loud. Use whatever attenuation you think you need.... I would build the amp first and then figure that out. I ...
