Traynor YSR-1 Custom Reverb Amplifier Head

This is a vintage Traynor YSR-1 Custom Reverb guitar amplifier head, manufactured by Yorkville Sound Ltd. in Toronto, Canada. This specific unit features a robust construction typical of the late 1960s to early 1970s, characterized by its heavy-duty black 'elephant hide' Tolex covering over a wooden cabinet. The rear control panel is finished in black and white with metal toggle switches for 'Ground' and 'A.C. On/Off,' alongside an external speaker jack and a primary speaker output connected via a 1/4 inch cable. A notable feature is the CSA (Canadian Standards Association) logo and listing number LR 21877. The riveted manufacturer's plate identifies the model as YSR-1, specifying 115 Volts AC, 50-60 CY, and a 200 Watts power consumption rating. Below the chassis, vacuum tubes are visible, indicating this is a tube-driven circuit. The unit shows signs of vintage wear including surface dust, minor scuffs on the Tolex, and slight oxidation on the metal components. A prominent red 'CAUTION' sticker warns against operating without a connected speaker, a critical instruction for preserving the output transformer in such tube amplifiers. This model is well-regarded for its point-to-point hand-wired construction and durability.
