Question about Legacy LA838 Car Audio Amplifier
Ok im having similar problems as you seen up above. im not good with electronics as far as checking the B+ thing lol but my amps doin the same thing. i was intending to get my compacitor hooked up but i got set back b/c of money probs. So i had it for about 1 month and now its blowing my fuses and smoking (in amp that is). its smoking from the battery hook-up side.
Sounds like you may have a shorted switching Transistor in the switch mode power supply causing a short to ground. If you are technical enough. Remove power remove cover and do a continuity test on the transistors on the heatsink. non of them should read zero resistance between the three legs. in all connection configuration you use to hook up your meter. If one or Two or even all of them do you must replace with proper part.
