  • My M90a recently made an update to the capacitors and transistors for the drivers. I used KSA1381 and KSC3503 and UPW capacitors.The M90a sounds good now, but the light still doesn't turn on when I press the power button. I replaced the two bulbs (one covered with red and one covered with yellow) with other originals. No lights come on yet. I ask for your help. Thank you

    I don't think I can help, sorry. I think you are talking about the circuit protection indicator bulbs but I am not sure. On my M90 when the red light won't turn to yellow the amplifier will not operate and the last time it did this I took it to a repair shop. They did a good job as I have not had any problems with it for at least a year.

    These are great power amps and well worth repairing.
