Cute little Fender Champ, made in 1971.

It has the AA-764 layout (see pics).

It came in with new tubes, but still sounding off.

The 12AX7 is blown, as is one of the bypass caps.

The fuse is meant to be a 1 amp slo-blow. It had a 2 amp in it. Replacing it as well.

Will order new filter cap can, replace the two-prong wire, the 25-25 caps, an install a known good 12AX7 and see where we are...
