I just ordered tubes for a Fender Champ. I also snagged a 4000 ohm -> 8 ohm output transformer. Seeing as how a 7000 ohm winding is used on the original, this should give me 1.75x what the voltage ouput would be normally?

The output tube is a 6V6. Here's a simple configuration for a parafeed 6v6:

You could build something like the moonlight, but single ended with a resistor load rather than the output transformer. Then simply cascade the output into the gainclone (after attenuating it a bit first of course). If you were feeling very adventurous you could add a choke is series with the load resistor for some added pseudo-speaker mojo I suppose.

The object of this amp is not to fake a tube amp, but to build a low-power tube amp and buffer it with a GainClone.

I found a 6.7k to 300 ohms interstage transformer on eBay for 10$. Is this suitable for replacing the output transformer in a Fender Champ amplifier? They're usually 7k.

You can use just about any transformer, if you are prepared to experiement with the interface between the transformer and the gainclone.
