Re: T1RVT - STARTING TO GET P****D OFF NOW!
I just stumbled onto this post. Is help still needed? I have a pair of these in the basement and owned a half dozen over the years.
Traditionally the 8 inch speaker was intentionally wired out of phase on these amps as a noise & feedback supression technique.
I certaintly would be worried about the impact of shorting the output transformer for potential damage. If the amp was just serviced it may not have been ran long enough to damage the transformer.
If I remember correctly there is a trick to selecting the polarity tap off of the main speaker. If you pick the wrong side you effectivly short out the signal into the reverb can and won't get any sound. However you will hear the ambient reverb pan noise but no music. Do you hear any reverb?
Also, I had these amps look like they were wired correctly but if you look carefully their may be a break in the wire on the HFP/Attenuator circuit that is on the input to the reverb pan. Additionally on some of these amps Guild did not use a RCA connector into or out of the reverb pan. Instead they ran a hard wire through the reverb pan RCA(F) connector hole and soldered it directly to the input or output. I had at least one of these with a wire break so carefully remove the reverb pan and make sure all the in and out wires are connected.
