with core memory torroids on it? i think this might be a 40-bit register.
if you look on the bottom of the board you'll see the IC is thru-hole with
a fairly large footprint. we had flat-pak devices that were serface-mount
for both digital and analog parts but this certainly appears to be a
plastic moulded device, but i'll bet it's considerably larger than the ones
in your receiver...those two resistors are 1-watt size based on comparing
with the glass-cased diodes. it's a bit hard to see things in his photo
and with the thick conformal-coating over all the parts and solder. but you
can see one connection from the square pad in the corner farthest from the
plug-in connector has a separate lead that goes directly to the IC-like
great that you found it and posted the link!
