Berning ZH270 Upgrades

Hi All,

I love my Berning ZH270 Amplifier!  The only thing that’s missing is a bit of high treble ‘shimmer’. Any suggestions on who I can contact for upgrades or suggestions for tube choices or other adjustments that can be made to bring out some sparkle at the very top of this amp?

Thanks!

Just email David Berning. He is the only one other than maybe Mark Schneider of LTA that can work on these amps. Berning’s designs are extremely complicated and I would trust no one else to work on them. http://davidberning.com

The other option is to buy a new and improved Berning design made by Linear Tube Audio.

David is generally very responsive and easy to reach. I'd try again or better yet give him a call. He is a very nice man and easy to talk to.
