Parasound HCA 2200 Hum problems


If anyone out there is having problems with hum and noise with this amp, please contact me as I have modified a couple of units and they sound vastly improved after and quiet!

Hum thru both speaker and transformer mechanical hum when the power "loads up" i.e. the line voltage "dips". Mostly these units seem to have a buzz thru the speaker. Let me know if you have a problem and I can detail some easy mods for you.
