Look through the past forums regarding VTL. They have proven to be VERY unhelpful on 2nd hand VTL gear. It's why many audiophiles will not buy used VTL gear. It's unfortunate since it is considered some very nice gear
VTL information
I recently bought a pair of VTL Deluxe 240 monoblocks. The seller didn't have the owners manual. I contacted VTL and was told they don't have any information on amps that age (1993-1997). It has David Manley on the front of the amp too so I called them and was told they engineered them but they were made by VTL. Although they were more helpful still now information. If someone could help me with any information I would greatly appreciate it. I want to get them serviced before trying them and am anxious to hear them.
