HI Jerry, If it’s one of the surface mount VC1s that we made for a while, I can’t guarantee to fix it…. a lot of the parts are no longer available, but I’m happy to look at it and see if we can get it back to original performance….. I had a very early ‘brick’ in for service this week; it had been ‘modified’ and was not working. I was able to get it back to original spec and it’s wonderful!
