That would be cool. I'd like to see some gut shots of that amp. Do you know what model number it is? I might have a schematic for it or failing that I might be able to find one.

Looks like it is the same as the Gretch/Valco 6150:

Does yours have a 5Y3, 6V6, and a 12AX7?

Is it wired on terminal strips (point to point) or an eyelet/turret board?

On thing about that amp. The input stage is wired for grid-leak bias. Instead of cathode bias like a Champ. There is a large resistor from the grid to the ground (6.8meg)and the cathode is connected directly to ground.

Looks like a cool little amp.

Might as well. There is a section on the BBS devoted to modding the Champion 600. It isn't as active as the Valve Junior section, but there is some information.

I went to register & discovered that a certain tot_Ou_tard had already registered.

I can't be expected to remember everything that I've done in my life!

This includes choosing a password. It took me a while to figure that one out.
