Thanks for all the help. I just picked up a set of NOS SED 6550 "c" tubes from my local electronics house. He said they have been there for 15 years or so.
They are matched and according to him have about 30 hours on them.
I also found some Baldwin 12ax7 and some black sable 12ax7 that he had laying around. He matched all the tubes for me. All that for less than $100cash.
I will be putting them in this weekend and doing a good burn in of all the tubes
and see what I think.
My old ax12 were tested and one was below the well good bar. So one channel was sounding different.
He said he will look around to see if he can also match some KT88's for me.
I am looking forward to burning these in and giving them a listen.
I will let you know what I think.
Thanks again for the help.
