Crosley 515 trouble shooting
#1

I have a Crosley 515 been working on it for a while here is the link. http://www.nostalgiaair.org/PagesByModel...003373.pdf

I get no sound, hum or static.

Here is the what I've found so far. the speaker coil was open so I wound a new one and it reads 1048 ohms the choke is 538 ohms and I get continuity on the voice coil.
Tubes tested good.
the ant coil was open so I wound a coil with the taps per the print I'll strip the old one and take accurate data later if I can get some sound
I recapped and as I was checking the resistors most were way out so I replaced all of them except#20 the flex which was good and 21Z & 21Y(wire wound mounted on the back wall of the chassis) were open and I replaced them with ceramic 5 watt resistors.
The vol is 0-30k
Checked Continuity through 1st, 2nd IF and OSC and they look to be good (I have the resistance values)
The socket voltages were taken with the vol at max and there all with in 10% the one question I have here is on the 6D6 IF SU & K I can very that with the vol control and it goes from 0-94v?
I put a signal gen at the G on the 6B5 I get a very faint hum.
On the Filter caps 6Z the + is connected to the 80 heater neg to chassis
the 6Y the + to the circuits and the neg to the chassis is this right? I get 6z 277vdc & 6y 211vdc on the + side.
Went with a red pencil component by component and found some mistakes and corrected them
everything else looks good where do I go from here?????
