El Jeffe; possible maybe Silvertone 1451? Pic from
Silvertone World.
I found a discussion
here that indicates the 1451 - if that's what it is - is electronically the same as the 1430
Schematic here. Goes on the say that it runs on 12AU6, 50C5, and 35W4 tubes .... the recipe, for safety's sake, that requires an isolation transformer on one side of the incoming power. Our ChrisB added an isolation transformer to his Danelectro Cadet that has the same tube lineup discussed here on LTG
in this thread. The transformers are in the $20-$25 range and not that big a deal to put in. Likely 8" speekee.
