46-1209 restoration....very little reception and 60hz hum?
#11

I was just curious as to how i could bench test my radio without having to pull the cabinet.

I double checked my electrolytic wiring to the schematic. I am wired properly there. The hum is definitely 60hz or so, i can hear it before anything else warms up enough to come on.

Also, how loud do these radios get? I cant seem to get a signal level above "raised voice" level. Could this be due to a faulty output transformer? Ive injected signal into the grid of both the phono preamp and the PI stage, and im getting roughly the same audio ouput level.
