Title: Speedball OA - OB voltages [resolved]
Post by: Wagonpilot on December 24, 2022, 04:47:28 AM

Built my new speedball, and the small board passed checks, but large board output voltages seem high to me.

Looking for warm fuzzies from the collective.

Main Input voltage is 122.5 Vac
OA reads 112.5 Vdc
OB reads 110.3 Vdc

Manual says 75 to 100 is acceptable, but to expect +/- 10%

+12.5 volts on top of a 25 volt range just seemed.... ehh..

It sounds great, and everything is running like a top. Like I said, looking for a warm fuzzy.

I built a Speedball a couple weeks back and that is where my voltages ended up also (all 3 nearly exactly the same as yours). Amp is running superbly.

BTW, very nice build!
