The best way to check a regulator IC, sans schematic with voltages, is to replace it. If you have access to a good DMM, you can monitor the B+ on the the collector of the HOT. It should be around 130V +/- 10V, and should stay steady as beam current changes (brightness, contrast). I always check regulation by monitoring B+ while varying the screen control on the flyback. ----------------------- Bryan Thompson Spyder Byte Services Albuquerque, NM
