Hi friends,

By reading the posts in this forum, I see that most of you refer to Jon Soderberg as **the ** specialist for upgrading or repairing the THRESHOLD amplifiers.

The web sites and email address given on this forum or on this site reviews are:

www.vitageamprepair.com
www.rsvonline.net
jon.soderberg@rsvonline.net

but none ot them seem to exist...

Does one of you have the new URL of the Jon Soderberg company, or any other alternative for upgrading these wonderful Threshold amps ?

Thank you very much for your reply,

N.
