[NJARC] Hallicrafters SX-16

[Scott Roberts]

ARRRGGGHHHHH!!!

I just went to warm up the set to do some troubleshooting of the
BFO, and got something completely unexpected: a veritable
lightning storm in the rectifier tube! It was glowing purple and
yellow, with  electrical charges jumping all over the place
inside- looked like one of those Tesla balls, and heated up very
fast. I switched it off after a couple seconds. Hope the tube is
ok- I will check it after it cools off...

I am suspecting a transformer issue... Any thoughts? I have it
switched off, and unplugged, although I tried to get a reading
from the empty rectifier socket, all I got was real high: I need
to figure out the transformer ower connections, and what should
be where...

Frustrating- get one thing straight, another decides to go to ...
