Hello, All
New to the site. Found this place while doing a little research on class D amp repair. Starting a project now with 2 MTX 1501D amps. I have 4 of these monsters but only 1 working right. Its been a few years but I did fix a couple of 502 thunder amps, back in my school days, about this era. Looks to be very similar at first glance.
Looks to be a few guys around here that have quite a bit of knowledge on my model so i thought id join, document my project a bit and hopefully contribute something useful for someone else, and maybe get a couple pointers to help along the way.
The first amp has a capacitor and transistor, (Q263) burned out. Powers up.
The 2nd amp has a transformer burnt, and D326 is burnt. No other apparent signs of damage. Does not power up. That one I was just running test tones to adjust balance with its twin when it went. It was running a 63Hz sine @ 40Vp-p with a 4 Ohm load for about 2-3 min. when it let go.
Any one have any resources, board prints, schematics, O-scope screenshots, notes ect. they would be willing to share I would greatly appreciate it.
