Ok fine, it's really a Chupacabra. But it's got some voicing changes of my own and if the Yeti gets its own name... then this does too lol . All the Cali-type amps are the same anyway. Chassis, turret board, and all the hardware are from Ceriatone. I sourced everything else myself. Still waiting on the iron and a few components here and there. But figured I'd get this ball rolling.
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.

The heaters on the Soldanos is a bit of a mystery. Unless the heaters are DC, then surely the amp would be quieter if they were twisted.
Can you get more quiet than quiet? Because the amp is noise-free.
People go crazy about heater winding. But I've never experienced any real noise from the heater circuit, regardless of how they're wired. So, go figure. All I can say is using a straight run of bus wire is way easier and nicer looking!
Hum from heater AC is not much of an issue at the power tubes, because any hum is not amplified much. It can be more of a problem if the hum gets into V1a and amplified as much as your guitar signal.

Doesn't matter. You can twist the wires all you want or add DC, but it won't make hum that isn't there disappear.
The amp has straight bus wire at the preamp sockets as well. Still... no hum.
A lot of amps out there do the same. Diezel, Soldano, Framus, Bogner, Peters a bunch of others... they all use straight bus wire and none of them have any noise issues. I don't know why. Just the way it is.
I've asked on some other forums. But maybe y'all might be able to help?
This is how Ceriatone wires the input. Seems a bit strange to me. Can anybody shed some light on what's going on here, compared to say... having the 1M-to-ground Grid Leak BEFORE the 27K Grid Stopper, instead of AFTER? I've read this causes some small signal attenuation. Maybe not enough to really matter. But still, seems like a weird design choice...
