That's the amp from the Todd Epstein estate that had the #180 Dumble.

Anyone have any idea what mods were done to this Bassman? I've got a hacked up Bassman (someone else's hack job) in need of a new life.

Mepco-Electra metal films on the PI, plus orange drops. Too bad can't tell if the values are changed. Three chocodrop caps. Carbon comp PI cathode and tail resistor changed to carbon film, Piher/Beyschlag probably. Cathode bypass caps on V3 changed to Sprague 5uF.

I'll compare this layout with the stock Leo layout. Is '62 a 6G6A or 6G6B?

6G6B. Would take a lot of work to decipher those two pots.

Those PI vales are fairly critical so they more than likely drifted to far out of spec.. The 1'st channel (cathode follower TS) looks like it could be voiced more for bass guitar..For me this amp has a cool factor of about a 5.. :shock:

Pot- MV
3way switch - channel jumping and a pad for the bass channel?????

I can certainly understand a pad for the bass channel. The two 6G6B's that I built which had modded bass channels, the bass channel was much louder than the normal channel.
