Can't remember which model, Comstat 25, 25A, or 25B but somewhere in the
middle of its series, they changed the crystal mixing frequencies. Didn't
change the model number but followed it up with a service bulletin to the
retail stores who had service shops. The 25 series was a very hot retail
item for years.
If any of you are doing conversions and run across a bad crystal in the
mixer or oscillator bank, I may still have some available. When Lafayette
was closing down many of their stores, I acquired as many service parts
for their stuff as I could. I've been picking at this stuff for 20 years
but there's still a bunch in bags, boxes, etc.
