[time-nuts] WWV or Net Clock controlled oscillator

I have been soldering since I was in high-school (circa 1970s) and before that.

I have two additional Maas-Rowe Controllers here at home I can work with. However I do not want destroy them to the point of no return as finding used units relatively good condition is becoming more difficult.  Some of the integrated circuits are a bit difficult to come by also.

I don't know if anyone makes such a thing. But I can easily think of numbers of answers.
It depends on what the Mass Rowe will allow and how comfortable you are with a soldering iron.
I will guess you need to dig in and supply a better reference. I searched the web for mass rowe and it seems operating manuals are available but no schematics.
If you can figure out how to inject a new reference things get interesting.
It may be as simple as a tap off of the power transformer going to a squaring circuit.
Easy thoughts. Oven oscillator like 6 Mhz divided down.
Pictics a time nut makes them. Don't remember if there was a Mhz in and 60 Hz out.
Then you can go even more interesting with GPDSOs that are divided down to get the 60 Hz.
Good luck
