Stickman builds his first tube amp

Interesting side effect of the CF back panel:

It's very conductive, and makes for a great shield.

Seriously, I was poking around yesterday and noticed a whole lot more interference with the plate off.

Cool.

Does the weight reduction allow you to play faster? 🤣
 
Pretty soon I'mma gonna be winding my own transformers and rolling my own caps.

Once I learn how to create and destroy energy, then I will be done. For then I will have am become death, destroyer of worlds.

I rely on NO ONE!!!!!
 
Just wanted to provide an update RE: swapping the rectumfrier.

Yeah, better. The 5Y3 dropped my B+ too much. With the 250vac secondary I had a *ton* of sag when I dimed my volume control.

New B+ nodes:
313vdc
274vdc
237vdc

Plate: 295vdc
Screen: 272vdc
Cathode resistor: 17vdc

All within spec. I upped the plate dissipation a bit from the 5Y3, but I'm still up around 75%ish of the JJ 6V6S maximum.

Result is a bit more volume and punch. I like it. Sounds great with a harmonic percolator goosing the front end.

So, I'll be keeping the GZ34 in there. The 5Y3 will be going into my 5E3 build that is currently in progress.
