I found and corrected the problem I discovered as I was attempting IF alignment. I had the 1st. IF transformer secondary and tertiary windings swapped. I found it doing an ohm meter check. The secondary winding has about an 8-10 ohm resistance and the tertiary winding has less than 0.1 ohms resistance. I connected them to the correct points and the set quickly came into alignment. I found that with just this portion of alignment done, I already am getting signals on all bands and the push-buttons work but need adjusting for some local stations. This radio lives again!

Tomorrow or so I will get around to doing a complete alignment. For now I am happy. Christmas came early here!

Merry Christmas and a Happy, Healty and Prosperous New Year!

Joe
