Hi All

Does anyone here have any experience on these amps. Ive hunted for some schematic and nothing contacted bk star hoping they could help.

All 3 channels are working upto and out of V2. There are 3 voltage regs on the board. RE63 seems to be low at 1.2v out with about 19v input.Unloaed its at 8.5v .. Other 2 are 12+ and 12-

Has anybody taken note of the test point voltages

anybody any ideas

What is the part number of the regulator in question?

LM317T ive swapped the one's about and the suspect one is working in the other posistion. Something is dragging it down

What is it connected to?
+ & - 12 that work, are they for the opamps?
The dodgy one may be for the heaters.

It does supply the Op amps and ive found the problem there is a programmed ic which is getting hot on one place, burn spot on it. Job finished for the moment. customer hoping to get the ic out of blackstar !! best of luck. will have to go to blackstar..
