SOLD     this my second listing (have a second ad posted)  (4) Matched   Quad Set Gold Aero KT99  (same as Ei KT90)   $260         Jim McShane Favorite!

these  were used in my INT amp,  and have around maybe 400-500hrs,  these  are very long lasting tube. (Sold amp-  and they  been in storage since )  bought in  2014


IMO:  easily  beats any  of the current KT88/6550 tubes out there, this  is nothing  out there that sounds like these tubes, currently available!



will   ship  ONLY to USA, lower 48         Payment by  PayPal           PM   for info                 Shipping $ 8.99              All   handled by first come!



These are the Famous  Type ll  with heavy duty welding spots  and  have a  Long life span  and sound Incredible!


Great sounding tube, which is considered to be one of the very best of all KT90 tubes and could be used in the majority of 6550 and KT88 tube amps. Superbly transparent and dynamic – taking about dynamic, the tube has a phenomenal punch!

Forgot to mention these  were  made by  Ei of former Yugoslavia  (same  as  the great Ei KT90)

a few quotes from a trusty worthy tube dealer (Jim McShane)     from AA


"Type II - the best sonically of all the KT-90s (IMHO, it's a VERY small edge), excellent construction, excellent durability; 100% interchangeable with KT-88/6550"


"Durability wise, the type II is superb (as was the type I)"


" BTW, my first set of type Is lasted 11 years at 575 volts and 80 ma bias!


Really loved the Tubes,  but no longer  have a amp  for them
