Hi All,

I just recapped this radio and it plays, but does not have much volume and has a little static. This occurs with or w/o the antenna wire hooked up to the clip in the rear of the chassis. (Usually when I connect the antenna to any radio, It receives stations much louder and clearer.) When I touch the 1det (77) tube with the tip of my soldering iron, it plays loud and clear the way I would expect it to play after hooking up the antenna wire.

I checked the antenna coils before the RF amp and they are showing continuity as well as the coil before the 1 det. No opens. Going back and touching the plate of the 78 and either side of the 110 mmf capacitor with the iron just prior to the 77 tube gets great reception as well. I am not sure what to troubleshoot from here. I know the problem must be prior to this 110 mmf capacitor, but have no idea where. Any help would be appreciated.

Thanks,

Steve

Sounds like an alignment problem. Check your rf then your if coils for proper adjustment.

ps just looked at the diagram, check for plate and screen grid voltage on your rf amp tube.

Thanks Terry for your input. IThe voltages were very low and it turned out to be an open resistor between the kathode to ground on the 78 tube. It's playng well now.

That's great that it was an "easy" fix! The next suggestion was going to be the band switch (NO FUN AT ALL!!)
