My tube amp power supply is buzzing away Help

dynamat maybe?

I don't know about that anti-vibration stuff, but PS Audio makes some products to prevent transformer hum (Hum Buster, etc).

The hum is probably from too much DC in the power line (DC Offset). Blame your power company. While you can issolate the hum with "anti-vibration stuff"; fixing the power is the real solution.

The various power regeneration, balanced power, power issolation devices that use their own transformers to produce clean power will probably do the trick. However, the cheaper ones might hum themselves since they'll be getting the same lousy outside power (LOL!!).

Never tried the PSA Hum Buster, but I assume it works.

Power "conditioning" or "filtering" will not work.

The unit is plugged into a BPT 2. I am going to try this. Open up the unit and place the transformer on four cut strips of hard rubber. I will then tighen down the bolts using the rubber as both a washer and underpad.

I called Pete from Mcalister and he feels this will do the trick. This power supply is said to be very quiet. Seems mine had been dropped during shipping as the underside is bashed in about 1 inch under the transformer. All else looks fine, but the bottom metal plate in bent and I am pretty sure this fix will work.

I will write a full review of this amp soon. But I will say this now. It is easily the best buy I have ever run accross in high end audio. $995 new and I paid $600 used. One of the very best amps I have had the pleasure of owning. Does not take a backseat to any amp I have owned costing up to $9500. Pure and simple.

I will let you know if this fix works. Pete said there is no need to buy that expensive stuff that comes in sheets. Just use the rubber from a $5 black bunge cord. I like that!
