G'day Theo,
here is what a quick look give me:
The Up-conv. LO is CCIR Ch69 with a crystal freq. of 71.095MHz
the Up-conv. has switchable AGC and
pre correction (I assume Group-Delay.)
The Down-conv. is Aus. Ch2 with a Siemens SAW OFW64950 IF filter.

The linear amp. is in two section each with it's own heat-sink.
The driver amp is a BLW32 /BLW33 Push-Pull followed by a
BLW34 Push-Pull final stage. The amps has a fan cooling.
The psu is linear, and on the back has a 24V DC input.



Cheers,
Mick.
