droptrd said:you can try Bob @ eurotubes. He does his own testing after the factory tests. Bob is very tube savy and only sells the very best JJ's. I bought a set of JJ KT88's from him for my mesa DR, and they were 10 times better sounding than the set i bought previously from tube depot. And Im not really into the JJ's. If you dig the JJ's, Eurotubes is the only way to go!
It's certainly an interesting option....I have a pair of Ruby KT-88s that I think may have been made in the same factory as the JJs...the Ruby's sound better...a little more defined and less tubby in the low end.
However the Gold Lion are night and day better sounding than the JJs or the Rubys...for only an extra $20 per pair.
