Hi Bob, thx a lot. Now I can keep it on my list and try to get it on the second Hand market in a couple of years . Its a bit too much for my hobby budget.  I am only interested in the Audio frequences below 50mhz range, so GHz is not important at the Moment for me Kind regards  Norman

Hi, So, on that note. I am surprised that I have not seen popular telecom rubidiums being reverse-engineered. For instance, the LPRO-101 should have been reverse-engineered a long time. Some of the circuitry is known from patents, but those do not build up a complete schematic. I've

Hi Well, if I could keep a 5065 running without repairs for more than a couple years I might be more willing to agree with you. What makes the 5065 different is that you have schematics and can do repairs. When the telecom gizmos die, there’s not much to fall back on. They were designed to run

Hello Time-Nuts, No offense Bob, but I would like to take issue with your statement 'Rb standards have a finite life'. There are time-nuts on this list of every skill and knowledge level and I would like to keep the information as correct as possible. My feeling is this is not a true statement.

Hi Rb standards have a finite life. Just how long that is depends a lot on how good a job the heatsink on them did as well as the run time. They do die of fairly normal random stuff as well. Like just about everything designed in the last 30 years, schematics and field repair manuals simply
