[Boatanchors] Viking II audio

[Garey Barrell]

Larry -

Yep, common problem in the Viking I and II.  Antique Electronic Supply used to have a replacement. If not, check with Hammond Transformer.

Don't bother with an 'original', the original transformer was overloaded, I think the primary winding was only specified for 15 mA DC??

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?
