Thank to all of those who helped me with info on the re-installation of my lost PTO. After quickly going through all of the modules (changing paper caps, out of tolerance resistors, cleaning connectors etc) this receiver nows received on all frequencies. The sensitivity is not great but much better than before.

 The big problem that I have now is distorted audio. I'm hoping that doing an alignment will help with distortion. Any suggestions are welcome.

After I get this unit playing close to where it is suppose to,  I'm going to go through each module with a fine tooth comb. 

I have found 1 bad crystal Y411 (16.0 MHZ) and the Function rotary switch is bad. I'm leaving it on and not turning the knob for now, using a variac to turn it on and off. I have changed the crystal from my second set, and get by with the switch problem until I can get a replacement. The bigest problem is I cannot switch over to the CAL position. The contacts on the switch are bent and ready to break. I had to play with it to get it to operate at all.

Thanks & 73's
