Genelex Gold Lion KT-88 reissued tubes

For Pentas (and GL's too) I think Doug at http://www.dougstubes.com does a great job w/ matching and general QC. His prices are very reasonable (I remember thinking his shipping charges were sane as well :-) Unlike some tube sellers whom I won't mention, he doesnt pretend to know what you (or your equipment) require. On the other hand, he'll warn you away from danger ;-) So call him if you have detailed questions -- just don't ask him what you'll like!

I run these in my Quicksilvers mid mono's
They work and sound great,I did not like them for the first 150 hours or so, as they were bright sounding,they mellowed out now, and are smooth now with great detail,tone and dynamics.
I would get them again.

Have cary v-12r's vertically bi-amping alon IV Mk II speakers. am very happy with the gold lion kt88 tubes. only had two go bad in 2 years. sound and imaging is superb

I replaced Groove Tube KT88's with the Genalex's in my MFA M120 amps and the improvements were dramatic. The GL's are lovely-sounding tubes at all frequencies. They're probably not even burned in yet,either. :)

I have also had problems with Genelex Gold Lion KT-88 thermal runaway causing damage to Jadis JA30. While they worked they sounded great but would not try these again no matter what the sonic benefit.
