Fuse problem

[vanlifeson]

Hello, I have a golden eagle, Mark one.
The transmitter shut off on me out of the blue. I checked the fuse and the fuse was blown. I put another fuse in the radio and the fuse does not blow now, and the radio does not turn on. I’m talking about the transmitter. Any ideas?

This is the 1967 or 1968 transmitter.

If it has original filter capacitors, this is a common way for them to fail. A short develops in one section of the 3-section capacitor. Fuse blows.

Time passes, the filter cools down a bit. The chemistry inside will now form a layer of insulating aluminum oxide over the shorted area inside the capacitor.

This removes the original short circuit.

I would check for damage to rectifiers and resistors in the B+ circuit.

Every electrolytic capacitor in the transmitter should get changed whether it tests bad or not. The small and large ones, both. Age alone dictates this.

This may not be what happened to your transmitter, but it's a sequence we have seen play out in the past.
