Hi Bill & George
How about injecting the Crystal Eliminator signal via the "XTAL LOCK" socket? The Crystal Eliminator signal via the "XTAL LOCK" socket must be AC-coupled via a 1 nF capacitor - and the signal might need to be attenuated and terminated with 50 ohm?
If so, the square wave will be bandpass filtered and a fine sine wave will appear on V2 cathode. C59 might be disconnected, so V8 do not oscillate - maybe it is not necessary?
