Been a while since I visited the phorum. Now I need some help trying to find a schematic for a Philco model 531. Beitman has nothing, Rider has a pictorial that has no component or wiring info. Fell in love with this since it's the first year for Philco and the beautiful walnut cabinet. So, unless I can get a schematic I'll have to turn up the Variac very carefully. But before doing that perhaps I can get some help here.
1. First I should mention that I have a Model 86 that the chassis is identical but the similarity ends there. The 531 apparently used a separately powered speaker (which is missing) as did all the table models in 1928. So a PM speaker would be an obvious solution.
2. I'll surely need info on the filter caps. any help will be greatly appreciated.
