Yes, it's from the sixties and probably uses Luxman output trannies, of very high quality. I could probably be able to figure out the fopur wire connections, but I would have to see the underside of the amp and internals of the speaker. Thus, you must sell me the system...
Unfortunately, the coupling caps on these, do not stand the test of time, as with many vintage amps. The amp can sound very nice, even without the special feedback network, using normal speakers.
There are actually two feedback networks. One of them is connected within the amp, like most tube amps, from a speaker tap back to the smaller tubes. I recall that the output transformer voice coil connections, inside the amp, can go to a different speaker, using wire you supply.
I would very much like to buy this amp...
