Sencore CR7000 repair update
Matt was able to repair both units. One had a blown G1 regulator transistor. The other had a blown -12V regulator and 3 other IC's!!. I think most of these were used on video game monitor CRT's. Probably had the leads from the universal adapters short to B+ or didn't discharge the HV anodes. He said he never has seen any damage like this to these before.These are usually very trouble free (Thank God). There is protection built in, but there must have been extremely high voltage spikes to cause the damage. Particularly on the second unit. I tried them on three different crts and get the same results on both. Thanks for the help!!...Jeff
