Title: Crack/Speedball big board voltages high [resolved]
Post by: Rabco on May 09, 2023, 01:58:01 PM

Hello. My small board numbers for voltage were all on the money. My Big Board numbers are as follows:
OA 115v; OB 112.4; G 0v; B+ 185.V
I feel a little silly as these numbers for OA & OB are very close to OK. But I thought I’d check. Better to be safe than sorry. Thanks!

You may have a very high emission 6080, which will produce slightly higher cathode voltages to hit the target current, so I wouldn't be too concerned about that.
