I have a 1970s Vintage Traynor YGL-3A mark 3 100W Tube Guitar Amplifier Head for sale in good condition. Appears to be all original as far as I know. It does work, however, it will need a full set of tubes to function, hence the low price. People compare these old Traynors to the Vintage Marshall Plexi lifiers, but this model sounds more like a Fender Twin Reverb minus the weight of a combo lifier. They are built like a tank with massive Hammond transformers. The best value in vintage guitar lifiers undoubtedly. Cash or trades possible for PA speakers, lifiers, microphones, etc. Thanks for looking.
