a tube amplifier repair technician

Bob Backert is a first rate technician, who has done several mods for me. I recommended him highly.

Bob Backert is not just a repair guy, he designs and installs circuit boards specific to his customer's listening preference; he does a wonderful job at a reasonable price. In short, his work enables my tube amps and pre-amp produce such natural and realistic sound like I've never heard from any high end audio gear.

Lucky, your name sounds familiar.
Ever been in QFS showrooms???
I have met there a guy name Lucky .........maybe it is you?
The lucky , I know
modded his Jolida monos and thought about Cyber Reference 2.2 or something like that.
If you are that guy...........I want to thank you....because your experiences with Bob and his work played a big part for me in choosing that road.

Yeap! it's me. I saw your amps at Bob's when I picked up my pre-amp. Here's hoping the mods has enhanced your listening pleasure.

Yes it did and I am hungry for more.
How is your preamp ????
