Does anyone have the amp guts of a Boss Riot R3400D, I believe the owner of this amp thought he was fixing this amp. But really messed it up. I need to know the correct resistor value for R11, R27. and R28. By the PS Fets.
They measure 10ohm, but this amp was worked on by someone else, I think the owner. These resistors were not put in by factory, can tell by the way the legs are bent. The soldering was awful, leads not cut off.
I dont have an output on the driver board to the outputs. I have a good signal off the KA3525a, all the voltages are correct. Same as in your guide. Not exactly sure how the low and high drives run through this board.
Perry I am getting 1.15v across the opto terminals for the on switch for the driver board 3 and 4, 4 black probe and 3 red. I am getting 86.3 across the 5 and 6.
