The manufacturer again did not honor his given word - this new unit has a GU84B installed, instead of the original GU78B (which the manufacturer in the past used in all his 3 k W amps).Upon request, no technical specifications of the altered amp have been received until today.The GU84B is known to give less plate dissipation than the GU78B - upon arrival, the blower of this new unit was not functioning.Incorrect blower wirings had to be corrected - the anchor holes of the old transformer did not line up with the holes in the new amp, new holes had to be drilled - the manufacturer now (May 2008, go figure) claims the first unit went faulty due to nicotine in the tube socket and hence no warranty is applicable for the new unit.Blue Book of Guitar Amplifier Values Online Subscription The Blue Book of Guitar Amplifiers is available through our website as an online subscription!
