Issue #19 of Vacuum Tube Valley did comprehensive listening test with current production and NOS KT-88 and 6550 tubes. You should check it out.
time to discuss kt-88's
It is time to retube. I have quicksilver 90's, and I understand different amps like, or may like, different tubes. I have searched the archives and found little discussion on kt-88 types. I have also wacthed a few post go through without a responce on different amps seeking advice on which tube that use kt-88's.
There are more options for kt-88's lately from svetlana, sovtek, jj and electro-harmonix. I feel that we, as audiogonners, should be discussing them. What are your opinions of these different tubes? What are the differences between them, how do they compare to n.o.s.? Any great bargains or sleepers? ect.
