Marty - Check all the playfield fuses and EVERY coil on the machine.
I have three driver boards in front of me, and all three have still got the original transistors (8026). So if you have the 2n3055 transistors installed, then the ORIGINALS may have been replaced at some stage. Someone may have replaced the transistors due to a fault during its route days.
I'm measuring .674 on all collectors, nothing on the emitter. This is with the board out of circuit. All my boards are out of projects, so they are untested.
You are welcome to borrow my board.
Thanks Nino,
Been away for a couple of days. AP is very hard to read on a mobile phone! - and expensive...
Interesting that you are getting similar readings....hmm
