one dead osc transformer.

edit--

thought as much, hopeless. not fixable. quite dead.

I'd carefully slice open the paper on the transformer and have a look. You have nothing to loose. Sometimes the magnet wire corrodes open close to where it solders to the colored leads or the outer layer of winding develops an open...

I had a vert Osc transformer in a Raytheon porthole where mice had chewed it up and I had to go down a layer to get back continuity in the open winding...It has ran decently on that lower turns count since then.
