Title: Someone say the 6P15P is a good for audio and usable as el84 ... is it real?
Post by: kagliostro on May 29, 2015, 02:05:59 am

Sometime happens to read that the 6P15P (6П15П) is an equivalent of the EL83 - SV83 tube

claimed to be a good tube for Audio output purpose (and usable as an EL84/6BQ5)

I've used the 6P14P (7189 equivalent) in hifi and guitar amps and found it to be a perfectly good tube

6P15P is closer to the EL84 than the EL83, and can be used as a substitute with the g3 pin connected to the cathode externally.

300V 9W = 10k load resistance


I saw a bunch of Russian EL83s going for a song the other day
