Hi Bill, I searched for the 1234 manual you said you posted, but came up blank. I had seen the Telonic threads earlier (including the one you mentioned:
https://www.vintage-radio.net/forum/...ad.php?t=71151) but I didn't see any manuals or circuit diagrams. Are documents posted within threads or somewhere else?
It's interesting you should mention wavetek, as I was recently looking at the circuit diagram for a 1062 (
