The fuse is there to protect the radio.
INcreaSiNG THE fuse size only creates more problems.
The capacitors are there for a purpose also.


OK so far.

When resurrecting old radios it is very important to bring the power up
slowly with a Variac.
Because you did not do that, you are screwed.


The vaiac is a good idea, but not essential.

I doubt if just putting fuses into it, along with capacitors is going to
solve the problem.


Old capacitors are just about the only thing that go bad from sitting.

A tube can get gassy while sitting, but it isn't common nor hard to determine.

Swans were a POS even when they were new.


Most people think they were pretty good for their time.

Your best bet is to shine it up real nice and use it as a conversation
piece.


I was wondering when you would go off the deep end...


I purchased a Yaesu FTDX-400 from an online auction. I have not
attempted to test the transmitter as I lack a suitable antenna or
dummy load. However after some time listening to 40 metres
a circuit breaker in a power board popped out. I reset the CB
and there was a loud bang and a puff of smoke from the area
of the power supply. A quick look under the chassis did not show
anything obvious.

I paid less than AU$100 including freight so I figure it would be
worth that much still to a valve enthusiast.

Biologists agree that descent with modification is one of the most reliably
established facts in science. Discoveries in evolutionary biology have made
a significant impact not just within the traditional branches of biology,
but also in other academic disciplines (e.g., anthropology and psychology)
and on society at large.
