buying (NOS) tubes online

Another vote for Andy Bowman. I have used him on a number of occasions over the years. He can be trusted and he will steer you in the right direction.

I bought matched set, hated their sound. he had me break them in for 60 hours (just on, no signal needed), then decide.

still didn't like them. I picked a different tube, 1/2 price of original pick. he let me return, gave me a refund for the cost difference, only cost me the extra shipping. 2nd pick sound terrific.

Buy from reputable sellers vintage tube  dot net,

vintage tube services , Brant Jesse audio, viva tubes , and a few others 

Also check out Vivatubes for older production Soviet replacements.

For the 6N1P's older (1970's) Vokshod versions should be warmer sounding than later Vokshod and Reflektor versions.

Getting into 6922 types to sub for 6N1P will up the cost substantially.

Not aware of any subs for the 6N6P.

@inna i see you deleted your post about not liking Brent Jesse. Why? 
 

my vote is for Brent and Andy for NOS. I try to never buy off eBay because anyone can put down test results and even show a picture of the tube tester that is biased wrong to produce good results. If Andy sold via online in a quick fashion that would be great but because of the slow wait I always go to Brent Jesse. Much quicker.
