Hey guys - I put a new power tube in my 8 , an NOS Russian 6N14N-EB. Man , it's nice nice nice nice!! From my research , the "EB" (which is aka "EN" - the Russian "B" is an "N" ) means it's a ruggedized military tube for vibration resistance and extended life (5,000 hours ) Anyway , just wanted to pass it along. Sounds glorious! And not too expensive. Got it from Dougs , here's the link: www.dougstubes.com/power-tubes/el84-6bq5/nos-6n14n-eb.htmlPS- I went for the"average distortion" rating he offers.

Just stuck a pair of these in my Maz JR from a UK supplier( NOS 1970). From a couple hours playing they are very nice tubes. Put in a brand new matched pair TAD STR monday and redplating and buzzing from the off. Also got 2 matched pairs labelled Phillips 6p14p but sovtek markings on them and date code 1980. Sound very nice in my 1974x but still got to try them in the Maz.

Used to be able to buy these cheap in bulk. Great bright clear tubes with a strong midrange. The bright mellows as they age. Somewhere I have a chart of the five or six levels (letters after the hyphen)... They are rated by life expectancy (hours), and durability (resistance to vibration abuse). The Russian used to make very durable tubes.

All these lamps have the identical characteristic. BUT.....Differ time of a life
6P14P - 3000hr 6P14P-V - 1000hr 6P14P-EV - 5000hr 6P14P-ER - >10000hr 6P14P-K - 3000hr and tube is steady against vibration!!!! This tube is very rare.
Also tubes 6P14P-EV and 6P14P-EB It is one type tube.

Fwiw, in the Cyrillic alphabet, which is what Russian uses, what appears as a B or b shape is phonetically closer to our V or v. But there is another letter that looks somewhat like a "b" with an added line; it covers the "b sound" from English. What looks like N or n is more akin to the Greek letter pi: it produces the "p" sound. And what looks like a "p" when written is roughly equivalent to English "r" (and Greek rho, which its shape resembles).
I think tube labeling may reflect hybrids of Cyrillic and English alphabets.
