I believe I need to rebuild the HV section for my Bad Cats display. The +100 volt pin has 0 volts. In looking at the parts I need to do so, according to Clay's guide, I need MJE340, which looks to be 300 volts instead of MJE 15030, which is 150 volts. MJE 15030, which is recommended, seems to be no longer made. Is is okay to use MJE 340 at Q1?
