I'm working on a restoration of a Zenith tabletop radio/turntable that I bought at the closing of an electronics store.  After doing a recap of the most obvious capacitors, I tested the voltages of the tubes according to the scematics and all of the voltages came in almost right on with two exceptions:

1. 6AQ6 - Pin 7 should be 48V and it came in at 30V.  I bought a new tube and the voltage measured 37V, an improvement, but clearly something still wrong.

2. I was not able to get any reading out of the Phono Pre-Amp (12J5) even after buying a replacement bulb.  Of course, I have the radio part of the device out of the shell and the turntable is not connected so that may have something to do with this.  Right or wrong?

3. I am unable to get a signal on the radio, just some static and a few spots where it perks up, but no meaningful sound.  I don't think that there's an antenna connected so would that be the reason for this or is there a problem elsewhere?

I'm looking for any direction to help with these items.

thanks you in advance!

Does anyone know the specifications (or can read the schematics) for the dial bulb of this model?  I have the burned out one on hand, but it has no specs written on it and the parts list in the schematics only calls it PL-1.  It's a bayonet style.

Thanks!
