Its been a long time, about 5+ years or so since the last time I repaired a car audio amplifier.
So, Starting to pick some of that up again, and unfortunately, I have lost my sheets and reference charts ive built up over time for some of the transistors that I got from digikey. Not to mention, the email address and password to the old digikey account I had so thats gone too since it was at another work place.
Anyways, Working on a couple JL Amplifiers, and I cant remember what digikey or mouser cross-references were good for the power supply driver transistors marked UY and WY, As well as the C3207/A1070 transistors.
the IRF540s are shorted in one of the 4 channels, and with those removed, there are a couple LEDs on the driver card that wont light up either without the transistors in circuit. I cannot remember if this is normal or not, its been awhile. But I digress.
any ideas? Thanks.
