Working on this GC-1195....
I need to replace the diodes in the power supply (along with the two electrolytic caps. For some reason Heathkit used different diodes for (D101,102) and (D103,104). D101,102 are three amp diodes while D103,104 are 1 amp diodes. It's my intention to use three amp diodes (NTE-156) to replace all four diodes. Then self doubt crept in and I am questioning my choice. Is there any reason you can think of that you can think of, other than cost savings, that Heathkit engineers used diodes of differing current ratings in this full wave bridge? Note that the emitter of Q1 goes off to power the incandescent bulbs of the display segments. Q1 is sourced from the center tap of the transformer. So, can I simply use 4 three amp diodes or am I missing something?? Thanks -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
