Need Tubes

Kevin has a big business to run, there is no way to Kevin has the same amount of time like he had 20 years ago. I still get great service from Upscale.

P.S. You also get a 72 hour burn-in (for power tubes) and grading for no additional cost.

My experience with JJ tubes (except a rectifier that works fine) is that they're mediocre at best. A pair of JJ KT77s was so bad in my Dennis Had SEP amp that it put me off 77s altogether until I finally tried a pair of vastly superior new Gold Lions...JJ 6SN7GTBs were also pretty lame, but cheap enough I bought some out of curiosity anyway...they will sadly languish in my tube drawer as NOS GEs soldier on. Regarding the JJ GZ34S, it came with my Had amp originally but I prefer a 274B as it's larger and just looks cool.

site: thetubestore or tubedepot  for new tubes.  Vintage tube services for NOS.

Andy at vintage tube and RAM get all my tube business, both have off the charts test gear and grading.
