[Hallicrafters] solid state device

[Ian]

It's likely a plug-in solid state diode module.  They were common in the
1960s and 70s and widely available to plug in to replace a FW rectifier.

It is likely though that it does NOT contain dropping resistors though.

Take it out and measure between anodes and cathode with ohmmeter in both
directions and see what you find.

After a  closer examination of my sx101a I see what must be some kind of a
solid state device mounted where the 5y3 rectifier goes.. It looks like a
standard 8 pin tube base but it is made up of a solid base like material. It
is approx. 1" in dia. and maybe 7/8" high. It rectifies well and has an
output of about 285v on both plate pins and 371v on the heater pins.

Anyone know what this device is as there are no markings on it. I'm guessing
that it probably had a decal label on the flat top at one time.

Thanks Jack
