[QUOTE="Family_Dog, post: 981536, member: 82"] No, that would possibly result in lower bass but would not cause the problem. The 1k resistor you mentioned - is it the one between pin 4 (counting clockwise from below the valve, from the spigot) and the OPT? That is to suppress spurious oscillations, if it has blown then you could well have a problem with that particular valve having an internal short, or even the cathode bypass cap. -F_D [/QUOTE]
