Before installing speedball all my voltages and resistances where acceptable except that the rca pins read no resistance, but i was told that was fine.
7 and 9 not reading a resistance voltage as well as b3, b6 and still both rca jacks center pins
I dont believe i damaged anything but i plugged it in briefly even though i defiantly shouldn't have.
All Leds are functional
T1 7.5 v
t2 202v
after getting those 2 voltages i unplugged it asap
-
I tested oa and ob on the speedball and neither show any reading for resistance
-
Measuring the resistance at terminals 7 and 9 is not part of the installation instructions on the Speedball.
Did you put the first small PC board on and then do the voltage tests before proceeding?
-
the small boards voltages are all fine and well, ignore everything else i said before i was looking at a different manual because i'm a doofus.
Oa reads 110-120 on the big board and ob reads 120-135
their is heavy static on the right channel and occasional cut out in sound
-
Did you listen to the Crack before proceeding with the big board? A cutout in sound will generally be accompanied by a change in voltage.
One test that can be popular is to poke around the circuit with a wood chopstick with some inexpensive headphones plugged in. That can help you find the problematic joint(s).

I had it assembled already but was having problems, i just re soldered every joint and that did the trick. Thanks :D
