<strikethrough>Weird! Nothing here makes me think this amp was made by Fender. Overseas clone?</strikethrough >

Yeah not sure if it's a real dumble if not I can move to discussion as a 'debunking' page but with the formica and components my limited experience says it 'could' be legit.

Thanks for sharing Phil.

Oh I can move it, I thought dumble files was for pictures of real dumbles. This is seemly one. If you think it doesn't belong, though, I'll move it.

Would Dumble use the Illinois Caps? Or maybe they were replaced...

When that amp was built, IC did not make caps that looked like that. Also the power supply dropper resistors (2W TE Conn) were not in production when this amp was built.

FWIW, I really wish techs would not replace those when recapping. CERTAINLY NOT in an amp like that. :roll:
