U1 is a solid state relay on the HV transformer 2ma AC from the front panel HV switch activates it.

Add a second fuse for 240vac ... mine just had one
Not much factory documentation ... almost home-brew


Quoting Richard Solomon <>:

I picked one up yesterday at a
local Flea Market. I was told it
popped the Main Fuse, but the-
price was right.

On a schematic I located, there
is an item marked U1, 01750.

Since I have not found the Parts
List, can anyone tell me what it is
and it's purpose ?

Tnx es 73, Dick, W1KSZ
