The JJ El34s & 6CA7s are my go to.

Forget tube gear....there are so many solid state amps that are amazing

I took a look at VIVA tubes and it seems they are fully stocked. I guess I have been looking for tube in all the wrong places! 😂 

@hiendmmoe For what it is worth I purchased some Russian preamp tubes that were advertised as New, NOS and Matched.  When they arrived they were not new. The boxes had testing results that were not anywhere close to being matched. When I tested them with a calibrated Hickok 600a tester they tested well below the new ranges.  Absolutely unacceptable.  To their credit they approved the return and credited all costs including shipping both ways. Beware their ad copy is misleading.

I've ordered from VIVA new production Psvane KT88s as well as NOS Russian 7189A power tubes, no issues
