I have 3 mast mounted nuvistor pre amps less power supplies. I was

as of yet I havent been able to find it. The pre amps are mount in a
somewhat egg shaped plastic container with twin lead connections on
them. Im not sure of the manufacturer. Schematics on the amplifiers
and power supplies would be nice. Directions on doing the mod would be
great. There are plans for ham band nuvistor preamps around so if I
could figure out what I have it shouldnt be that difficult to conver
it to what I want. Besides that it will give me something to do with
these old 6cw4s.

You would do good to find a 70's or earlier ARRL handbook. There were
many articles about Nuvistors.

I used to have access to the handbooks of the 60s and early 70s. I
thought those were some of the best years. Im always on the lookout
for some but it seems a lot of other people share my opinion and dont
want to part with them.
