Hello
Has anyone replaced the amp that came in their Deep Hemp Sub?
I have two , both with the earlier Class AB "SPA250" plate amp. Both hum and one of them hums really badly ...rendering it almost unusable. It's not a ground loop and devices intended to block low-level DC voltage on the power cable have no impact on the hum.
I'd like to replace the plate amp with an aftermarket one...probably class D.
Parts Express has quite a few options at decent prices. I guess I'd be looking for something in the 250-300 watt range.
One issue is the cutout specs for the various plate amps are different so I'd have to fabricate a flange or new plate but that's not too difficult.
Has anyone does this and any options on various plate amps?
Conversely , has anyone successfully fixed their SPA250 plate amp on their Omega sub? I know the humming and intermittent popping are (or at least were) well known problems with this plate amp.
thanks
