Problems with my Berning ZH270

George, I have read that some knockoff Bernings are floating around. You might contact Dave Berning with your serial number. Also, Allan Bhagan might be a good resource for you. I can count the number of great dealers on 1 hand, and Allan is among the best. He knows more about the Berning than anyone. You can reach him at info@allanbhagan.info He sold me the ERS upgrade for the Berning which is an unbeleivable improvement. and wellfed, yes I am Larr'ys friend.

Hi. I don´t live in USA, but I bought my Berning from Allan, brand new. Yesterday I change my NOS Telefunken and it seems that the sound go better. I change the tubes inmediately after receiving the amp, I have not listen to music more than few hour with the original tubes. My fault.
Thank you very much for the help I have received from everyone.

George,

One question - what kind of rack/isolation support do you have your components resting on?

Hello gain, George.
Well, glad you got ZH from Allan because I had heard that outdated worn down ZH270s are floating in the used market.
I never mean to imply that the stock unit is inferior in any way, but cryoed output tubes will give you one notch up. ERS kit, in my case, would give another TWO notches up. And, yes, good feet (Stillpoints, specifically) would give further notch. Since I don't have your speaker and source, I don't have any more meaningful suggestion except for adding subwoofer. Hope you will find ZH an exceptional piece of equipment. Welcome to the club.

I have a Lovan Classic rack "upgraded" with a silestone shelf.
