Russian 6N3P

This is a rare Soviet-era 6N3P, produced in the 1970s at the October Factory in Vinnytsia, Ukraine.

If you are a 6N3P/5670 aficionado looking for vintage 6N3P/5670, this is a very interesting tube to try especially in comparison to 6N3Ps produced by Xpo-pul in Saratov during the same Soviet era.

The tube number and the logo are etched but somewhat faint. The tube comes in standard blue and yellow CCCP export boxes, with the October factory logo stamped on the lid.
