Sub amp issue

S7910S7910
in DIY
A couple years ago I built a 2.1 system for my younger brother. The sub used the SA70 and SD270 in 3 cubes tuned in the vicinity of 30Hz. The sub now only gives a 60hz hum even when fed a signal, and I suspect an issue with the amp.

Is this a known issue with the SA70, and if so is it repairable? Otherwise, if I just replace the amp with a new SA70 what are the chances of the amp failing again?

    Every plate amp I've owned has failed.  That said the Dayton 5 year warranty was almost enough to get me to try one again...

    I was hoping it'd last 8-10 years before going out, but I guess I give my brother a new plate amp for Christmas a bit more often.

    If you bought the plate amp from PE you should check with their tech support. I had a plate amp fail which I assumed was out of warranty and they fixed it for free.  Some time later the original problem showed up again and they replaced the amp.

    I'll check into that. Thanks Ron.
