Does anyone have a Schematic for a Fryette era VHT Pitbull 45 ?? I am having some issues with channel 2 and my local tech is not getting much response form the folks at Fryette amplification. Prior to taking the amp in for repair, I attempted to make contact with them regarding a schematic and/or the process for sending the amp to them for repair, but got no response. Is this normal ?? Any VHT or Fryette owners want to weigh in??
