Hey all,

I recently acquired a lightly used SuperZen. It sounds amazing in my near field setup, but I eventually noticed a slight hum. I chatted with Steve, and later ruled out bad tubes or a ground loop. The hum seems to be coming from the amp itself. I plugged it into an isolation transformer, but no change.

I'm wondering if I'm just being overly sensitive since the amp is so close to my chair. Do any other owners of the amp hear a slight hum/buzzing from the amp itself?

Thanks!

I also have a hum coming from the transformer as well as a low buzzing coming out of the speakers. Not sure if this is the norm. I didn't have this with my last tube amp. I do like the amp, would just like to loose the hum n buzz.

My SuperZen is very quiet. I have no hum.
