Hi!

Anyone can suggest closest Russian analog/substitute for 12BH7A? Used in push-pull amplifier to drive output stage.

Thanks in advance for any suggestions(s).

  LinuxGuru,
  
  The closest Russian substitute for the 12BH7 I know would be:
  
  http://store.triodestore.com/12elrustub.html
  
  - which is the Electro-Harmonix "12BH7EH", made in Russia. I believe the Russian designation is 6N6P
  
  Is there a reason you need to have a Russian 12BH7? :

  - as there are still quite a few good NOS available.
  
  I use the 12BH7 in an Audio Research SP8 preamp(power supply regulator) and 2 in McIntosh MC240 power amplifier and over the years bought a supply of NOS:
  
  12BH7 (3) 2, 1 TOTAL: 19 (> )
  
  1- GE- Brimar blk pl- NOS
  3- RCA grey pl, D- gtr, NOS
  3- RCA grey pl, halo gtr- NOS
  2- RCA- blk pl, U gtr -1949 -NOS
  3- Sylvania- grey pl, halo gtr- NOS
  1- GE- NOS
  1- Raytheon- blk pl, square gtr- US- NOS
  2- Raytheon- blk pl, sq gtr- US- NOS 1959
  2- RCA- blk pl, halo gtr -US -NOS
  1- CBS- blk plate, stirrup gtr- US - NOS
  
  The black plate RCA is supposed to be very good sounding as is the Brimar. The 2- RCA's from 1949 are the oldest tubes I have.
  
  Cheers,

    I had a huge amount of NOS Brimar with GE label 12BH7A a few years ago. I listed in lots of 5 and every auction was bought by a business in France.
