[QUOTE="alternativeroute, post: 47161, member: 1115"] Hi There, I am not sure if anyone on this can help me out. This weekend I had the fortune of picking up four QuadII valve amps and two Quad22 Controllers (I think we call them pre-amps these days). The amps came as a bonus filler with some turntables I was really after... Anyway - what I know about electronics is pretty dangerous. I have tried two of the QuadII's and hey-presto, plug and play, it works... Obviously the equipment is aged and in desperate need of some restoring. This I think is where my journey with valves will start... The question I have is the following: all four of the amps are missing a valve! Yet the two i tried still work! What does this mean? I suspect the units have been extensively modified before... I have attached some pictures if anyone has any ideas. Regards JQ ps. I also got a box with some spare valves...
