The Amp Garage

Wondering if someone has done it with 6AQ5. Probably the significant difference between 6AQ5 and 6V6 is that design center rating for max plate voltage is 275 vs 315. I understand spec is often ignored, but B+ at 395v is 120v over and that seems like a bit much. Is this worth trying with a lower vol...

Thanks. That was almost too quick. I was just returning to say, "oh, never mind, I looked at the pix of Francesca." AFA shielded and oscillation, I've built 7 amps in the last 4-5 years and am familiar with that problem. I appreciate that pointer on the volume pot. I'm a bit of a purist and tend to ...

I've build a few amps and am thinking about a TW Express. On the schematic, I see an unfamiliar symbol. Between the input jack and V1A, there is a circle around the grid input wire attached to a ground triangle. I hope this is clear. What is this thing? If left to my own invention, I'd guess this is...
