What Copper Cap would YOU put in a brown Concert?

[steel1953]

I've decided to install one and with all the range of voltage drop they have, I'm not sure which one would be more applicable for harp. Some drop as much as 50 volts!
FYI, I've went with most of what MWJB suggested as far as setting it up in the Vacumm Tube harp amps post.

Thanks! Brian

I'd stick to the stock diode for maximum punch, power & low end. Everybody I know that uses a Concert has the stock rectifier, if you drop the B+ the amp will just go middley and lose low end.

What have'nt you done from the post, what do you want more/less of?
