Title: Ceronix 1492: B+ test points?
Post by: jmartin on November 26, 2021, 12:21:02 PM

Perhaps my Google-Fu is weak, but I can't find the procedure or points for testing B+ on the 1492.

No crackle, black screen.

I'm new here, so this is probably a bit late.

According to the schematic, B+ is 127V. Looks like is can be measured at the cathode of power supply diode 252 (an FR205 diode), pin 6 of the FBT, and other places.

Thank you.  Yes, the game is long gone.  Got it sorted.
