The monitor test points will not help you, except to let you know its operating correctly.
I had an FRK-L that the lamp failed. I ran fine for 12 years (and it had more years on it, bought surplus). It was working fine and one day, I noticed it was not locked. I kept monthly logs and the data did no show any real changes. When I opened the unit I could see the lamp was firing and running - but the optical pumping/adsorptions transition occurs in less than a single percentage point. Most lamp failures occur because the glass gets a internal burned coating. Surplus lamps are not too expensive (usually under $50 or so)...and a new one - back when Efratom was in business, they wanted $400. I believe Symmetricom wants about 3 times that amount.... I can recommend Corby Dawson, who is on this list, should you need repairs. Brian Kirby KD4FM Richard W.
