I have recently obtained the holy grail for me - an 8566B. They are rare as hens teeth in Australia!
I have a 8568B as well and my phase noise floor is somewhere way down there on that machine ;) However it appears the internal 10Mhz reference had died on the new (old) 8566B. I haven't room on the bench due to 5 things going at once so I ran it up on the kitchen table for the benefit of the kids - they are going to inherit all this junk I guess :p I didn't plug an external standard in to check the rest of circuitry because that's down in the workshop. Perhaps I need a house standard output in the lounge? ;) Hmm Anyway, did some quick checks and I think the voltages are all there, but my manual has the 10811 oven assembly which the Pin outs are completely different. Anyone spied a 8566B manual with the Ovenaire OSC-49-61C connections? Or even just the connections so I can work on the Ovenaire on the bench. The output has a 10Mhz SMB on the right side and a row of six feed through caps on the left. Bottom to top 1. Black 2. Orange 3. Purple 4. Red 5. Black 6. Linked to pin 5. I guess It won't be too hard to work out by tracing the circuit but I like to leave the innards of these things undisturbed as much as possible.
