Tube amp humm, Power conditioner?
type: item
description: Hello, I'm concidering purchasing a power conditioner to help clean up some of my amp humm and noise. Is it likely that this would help? Can you suggest a specific type? I don't want to accidentally buy a high dollar power strip. What type of components should I be looking for? How much should I expect to spend? Can a couple hundred dollars do the trick? Thanks for your help, Pete

description: I think it is not a good idea. Think in terms of what a power conditioner does; it prevents overloads and controls the release of power to the amp during times of high demand. Exactly what you don't want.

description: You just missed the steal of the century. Picked this up for $120, after $50 rebate. Too bad the sale has ended. Not sure it would help with your hum, but it didn't break the bank and looks a hella lot cooler than my Topaz power conditioners........Colin http://www.buy.com/prod/monster_power_hts3500mkii_10_outlet_powercenter_w_stage_3_filtering/q/loc/111/PageFormat/40/imgNum/1/90119434.html#moreimg

Hum or Noise?

description: Peter, Are you having problems with hum or noise? If hum, the most common cause of it is ground loop and a power conditioner wouldn't help.

description: Just a thought. I do not think Monster unit this is a surge protector, or has filtering also does it? For about $150 you can buy a used Powervar hospital lab grade with voltage and line filtering on ebay. I have two Powervars now and a third one for my home theater coming. These filter and offer excellent protection since they were designed for high end sensitive laboratory equipment. These Powervars still sell new for ~$1200 for the model 12 that I have. They are a steal at around $200 used. For my audio system I added an additional level of dedicated line filtering for my two pairs of tube mono block amps into these Powervars. The background noise level dropped down to next to nothing. I have very sensitive 6' tall 2-way horn speakers at over 100dB efficient with 1 Watt at 1 Meter. Just another suggestion is all. John
