subwoofer amp

Just finished an SPL10 repair for a friend, here are some notes..... There's a decent video on YouTube that should help, biggest issue is a handful of 33uf caps buried in the power supply that go bad, high ESR readings. Tear down is not easy..... Power Supply: - Power Down/Double Check...

Hello everyone, I have a rather specific inquiry regarding the Velodyne HGS 18. I bought the subwoofer a few months ago, but there are certain frequencies that make the sub bottom out, (even with gain at less than one) which should essentially not be happening. Because there are lower...

Does anyone out there possibly know what spec audio taper and linear taper potentiometers an Energy AS-180 subwoofer takes? I dearly love this big old woofer and both pots are shot and need replacing. They are both labeled “100k”, but I’m uncertain as to wattage... Any thoughts out there? Thanks!

Hi all, I have 4 NHT SA3 subwoofer amplifiers. The only thing is.... only one of them works as I think it should. Another doesn't work at all (yes the fuse is good). The remaining 2 have a unique and somewhat disturbing quirk. A local friend and hard core audio restoration (EE) guy recommends I...
