Need Tubes

for arc ls25 mk 2 .... it runs russian 6h30p’s only, can’t roll tubes

mk 1 was still 6dj8/6922, this was the model changeover to the russian 'supertube' or so they called it

just buy from arc if cost is not a factor

or order from jim mcshane, upscale audio or thetubestore in canada to save some $, all these excellent tube vendors properly test tubes themselves before shipping, you will get good ones

I bought mine on ebay from seller wpc1896.

Brent Jesse has an excellent reputation, I certainly have had great experiences and saved money.

I tried some Sylvania’s, didn’t like their sound. They had me break them in 60 hours (simply on, no source needed), listen, still not happy, returned, got less costly GE’s, love their sound, got a full refund for the cost difference, no restocking fee, I just paid for mailing.

I don't care for current production tubes. For me NOS is the only way to go. I get mine from Vintage tube services /Andy Bowman or Brent Jesse Recording / Brent Jesse.
Good luck

Try Upscale Audio. They only sell tubes that have a record for being reliable. Many tubes are not. Got a matched set of 12 EH EL34's for less than $20 a piece. Tubes are fully tested and burned in for 72 hours. Performance (SQ) matched exactly with Kevin Deal's explanation of what to expect.
