Ok, I know it was a mistake, but I strayed from Philco. I picked up a Grunow 588. I got it for only $38.00, but now I'm stuck.
I replaced (very carefully) all the electrolytics and paper caps as well as any resistors that were out of range. The tubes were tested and replaced as necessary. All I get is a low hum. I get nothing if I touch the center lug on the vol control.

Any ideas?

Thanks,
Eric
