Thanks for the suggestion. BNP has aluminum stock that is black that engraves to gold lettering:Originally Posted by duhvoodooman

I hope so, I think this will be a cool build. One of the features of this amp is the inputs: one input is a single triode of the 12AX7. The other input is both triodes in parallel which gives slightly more gain and a bit more complexity in the tone due to the differences in the triodes.Originally Posted by duhvoodooman
As detailed in an earlier post, I'm using a NOS Custom Coil Unit. It is rated for 70-90mA, 290-0-290. It also has 5V and 6.3V taps. Instead of a 6.3V rectifier, I'm going to use a 5Y3 or 5V4 on the 5V tap. I built another amp with a 6.3V 6CA4 rectifier on the same filament winding as the other tubes which is a bad idea. If the recto ever shorts out, it will take out the tubes the output transformer. Using a 5Y3 is much safer. I should get about 300v plate volts, which I've found sounds very good in a PP EL84 amp. Also I can run the amp in true Class A. The only limiting factor is whether the OT can take it. Class A is inherently hard on transformers, especially ones made for Class AB operation.Originally Posted by duhvoodooman
The one thing I don't like about the Edcor transformers is the exposed solder tabs. It is inherently dangerous to have exposed B+ outside the chassis.
Cool, I'll check him out. :Originally Posted by duhvoodooman
One of my grad school professors lives in Saratoga Springs. He was my favorite, and one of the coolest people I've ever met.
