Help with Bosch 48
#1

Well i finally finished recapping the Bosch48 but its pulling way too much current, like 146watts. Somethings i know:
1. Transformer is putting out correct filament voltages
2. Resistance on 80 rectifier plates is 160ohms, 80ohms each side to ground.
3. 80 rectifier filament pins measure .1ohm
4. When 80 tube is pulled watts are 40.
5. All filter caps replaced are non polarized polys.

Anything i can try to verify if the transformer is good and also locate the source of the draw
