Mosconi AS200.2

Since I did this on every amp, I used a header to save the leads. You don't have to solder it in. Just putting it in the holes and putting a slight (angled) pressure on it made it connect on double-sided boards.

Cool, thanks for the tip. I will have to set one up like that.

Got the MOSFETs in today and got the amp tested, and it is working great. Thank you Perry for your assistance.

Spoke too soon, after getting around to fully testing the amp, I noticed that the highs are muffled. Gotta get it back torn apart and see what else is wrong.

Finally got back around to finishing this amp up and was able to confirm that the highs were being attenuated. I scoped the output from 20Hz to 20kHz and above ~500Hz the voltage of the output continued to decrease.

But as it turns out there was nothing wrong with it, the amp has the add-on bass knob RTC-MOS. This bass knob has a module G_RTC-CARD that installs in the input side of the amp. With this card installed it must automatically set the amp for subwoofer use. With it out the output level was consistent from 20Hz-20kHz.

Testing it now, it sounds awesome full range. Thanks again Perry for all the help.
