Well in preparation to modifying the Viking II audio, removing the 6AU6 tubes, enlarging the sockets to accommodate 9 pin types and using a 12AX7 to drive a 12BH7, i discovered the reason for my squeaky audio. The primary of the driver transformer was open. While in conversation with a couple local hams today on 40 AM, that topic came up. One fellow said that it seemed to be a natural thing in not only the Johnson rigs but Elmac as well that for some reason those transformers would open up. It happened to me! Now to find a replacement and get on with the mods. This was a pretty good reason for me not to have much modulator current, ya think?
This could be more fun than i want to have. Focusing the eyes in areas like this is getting to be more of a problem every day. Its the golden years that are causing it i'm sure!
