> This amp was a Japanese import around 1978. uses a pair of 3-500Zs. Entire
> amp weighs 90 pounds. Amp and PS are all one piece. Runs 3500 volts on the
> plates. 120 watts of drive gives 1500 watts out 160 to 10. The original
> bandswitch is bad. I have a JVC 9000 type for a replacement that is two
> wafers deep. This will fit in the same space as the original but I do not
> think the indexing matches the origianl therefore the tuned input switch
> will have to be bypassed. The tuned input switch shaft piggybacks the main
> bandswitch shaft and I am sure the indexing of the new switch does not
> match. For now you will have to bypass the tuned input or??? I have the
> original bandswitch almost entirely removed already. have copy of the
> which is poor but scat is intact. Front panel and cabinet are real clean.
> Will double box and ship UPS ground. Price is $500 with the tubes or $350
> w/o the tubes. Buyer covers UPS charges on 100 pounds (amp double boxed
> packing material) from 92139 San Diego. Be warned that shipping is not
> cheap.
