Yeah I have heard about that but I had no expectations re warranty. Although I have the original boxes I never had paperwork. Got biasing info from VTL website and took it with me. I was delighted the shop would take it on without schematics etc.
VTL repair success
Earlier this year I browsed many Audiogon posts related to CS issues on older VTL gear as I searched for a place to look at my Compact 80 monoblocks. One amp had developed a hum at idle. Annoying but still listenable. I did try to contact VTL directly via webpage and fully disclosed I am the second owner of these approx. 30 y/o amps. While I was not ignored, I did not get any suggestions on where I might take them in my general area (Kentucky). The shop that last re-tubed my amps had closed (retirement) and I could not find anyone else locally. Anyway, via www I finally found a shop in Nashville (British Audio) that works on home tube audio. Very busy shop and it took several weeks, but they diagnosed and replaced two filter capacitors, solving the hum. Very reasonable. Mentioning this in case anyone in the Southeast U.S. has a similar need.
