So i did a full recap on this radio and its running pretty good. The original 6A7 tested marginal so i got a NOS 6A7 off ebay and the radio is not happy with it especially the SW band. Starts to "whistle" in certain areas on the SW dial..

I was going to try tuning it up so i set my Signal generator to 454khz and the tuning gang fully meshed in an attempt to peak the IF section.. I am noticing i dont hear a tone till i open the tuning gang halfway. Is this normal or is my radio way off??

Works pretty well in the Broadcast band hooked to a longwire.

A picture of the radio in question is located in the November finds area...

I noticed the tuneup section doesnt cover the SW alignment.. Do i have the right schematic? The tubecount is spot on..

Thanks for your input..

Steve
