[HBR] Some Compactron modules

[Ian Wilson]

A few years back, I got part way through a receiver based
on the 'KCS Compactron' (in two of the last issues of GE
Ham News). Naturally I made some radical changes. My
version used a 9MHz IF (instead of 455kHz), Pullen mixers,
different tube lineup, etc. This had some promise but attempting
to use the 6AR11 (twin high-gm semiremote pentode, TV IF amp)
with inadequate shielding at 9MHz led to .. predictable results.

Anyway. I don't seem to do anything with this except kick it
around the floor. It was built on a number of single-sided PCB
"modules" using ugly, er, ground-plane construction. There are
three 5.5"x4.5" modules and one 9.5"x6" module. There is a
nice premixer 16MHz VFO (high-quality air variable and ceramic former
variable inductor, mixed with an 11MHz xtal osc). The modules are:

RF: 6BH11 (dual triode + pentode); 6AC10 (triple triode);
       VFO components and 9MHz homebrew filter

IF: 6AR11 (dual semiremote pentode)

BFO (9MHz)/Product detector: 6U10 (triple triode)

Audio/AGC: 6T10 (beam power pentode + shpar cutoff pentode);
           6U10 triple triode; small (8W) audio output transformer

The Compactrons were all NIB and have a few hours of
operation on them. The sockets are all high quality ceramic
12-pin Compactron.

I actually have schematics for all the modules (they may have
had work done on them but should save lots of detective work).

I would like $15 for the set of modules plus shipping from
92620. Happy to trade for something as long as it's smaller
and glowbug-oriented :)

Please reply off-list. First come first served.
