ADCOM 5450 Resistoe
I was Recently given an ADCOM 5450 car amplifier to repair. Amp goes into protection when powered on. So far, I’ve found a bad diode, two small resistors, and 2 damaged IRFP240’s. I’m trying to determine the correct value and wattage of the metal oxide (flame proof) resistor connected to each of these transistors.(Please see…

Tweeter noise when using high beam!
I have a problem with my aftermarket car audio system. The aftermarket tweeters in my Skoda Octavia 2001. After a lot or trail and error i finaly managed to the alternator whine in the tweeters by using a Helix CAP33, alternator noise suppressor. But i still have the problem when i toggle on or flash…

Bob Cordell’s Super Gain Clone PCB (LM3886) and a stripped-down version: Compact3886
In his book Designing Audio Power Amplifiers (2nd edition), Bob Cordell discusses a chipamp he designed around the National Semiconductor LM3886. Bob calls it the Super Gain Clone, and he summarizes its features as follows: 40 Watts per channel into 8 ohms from LM3886 devices The LM3886 is operated in inverting mode for best performance…
