Hi Dick,
regarding the 5334B, the "C Channel" is complete except for a pair of diode
rings, the prescaler and of course the connector. I'd say it's easier to
start with new parts rather than salvaging.

I've just added the "C" to a 5334B and it's remarkably easy.

- The original prescaler (MB506) is nothing special, but there are plenty of
pin compatible parts available. I've used a uBP1505 on an SO to DIP adapter.

- Couldn't find any quad diode rings, so I've use two series connected diode
pairs at each location (HSMS-2812).

- For the connector, I've used a panel mount SMA to N adapter. This has
allowed me to use semi-rigid inside the box.

Remember to remove the unused input cap (C327 or C328) when you decide which
input you'll use
