Guys, bought this Chinese/German Vincent sa-t7 preamp about 10 months ago, and a few days back after the warm up the left channel started to make a weird distorted thumping noise, which turned into a permanent loud hiss. Just the left channel. The volume level doesn't affect the noise. I already tried a different power amp and preamp, so the problem is the pre, and it's not tube-related (switched the channels, tried a new set of tubes). Going to ship it to Audio Advisor under their warranty, but still very curious what that could be. Any ideas? Appreciate your feedback.

FWIW, I found AA to be very good about warranty, posted on December 24, 2020 at 17:03:54 | |
