Re: Preferred Filter Cap Brands?

Tubedepot is having a 15% off sale right now. Go with the F&Ts. I'm not sure that they sound any better (I've used both), but they look more impressive, which doesn't hurt especially if you end up selling it in the future.

Re: Solid core wire - ok for heaters?

Fender used solid core for heaters back in the day. I've had many problems with amps, but solid core on the heaters was never one of them

Re: Trafo orientation

Great. With custom builds I usually test multiple positions for hum before committing to one direction or the other.

Re: 100W SSS Build with Amplified Nation Chassis

Sounds like a great plan! Not to be a stickler, but that's actually not an Amplified Nation chassis. That's a chassis that I designed and had fabricated a few years ago. I did sell 5 or 6 of them to Taylor at AN. Good luck with the build!

Re: Evolution of SSS

Ceriatone had access to a SSS and made their version based off that amp, I do not know what serial number the amp was. I'm ...

Re: Source for Fixed Bias VVR Boards

I've always just wired up the "VVR" circuits using a home made eyelet board. The circuit is very straight-forward.
