Many years ago I bought my first service monitor.
Com Ser Laboratoreis BR-1000A.
It seemed the company that made this monitor went out of business not too long after selling some of these.
This monitor worked like a champ. An older design and had soime strange ways of doing things but it covered most needs for ham and commercial radio repair. This particular unit happen to have the scope and trouble tracer add on kit.
One day in the shop I turned it on and the scope let the magic smoke out. Not a problem Just unplugged the scope unit and the generator still worked. I did tear the scope down later and removed some PIO caps that had exploded.
2 years later the display started to act up. Then the unit would stop generating. I finally had to retire the unit since there was no service info around and picked up a IFR 1200S.
12 years later I dug the unit out of the store room. Think I want to try and restore the old girl.
A few years ago I did run into some shematics and posted them on my web site. But these schematics have no voltages shown.
