In Reply to: RE: 6922 and 6SN7 Soviet Substitutes posted by immatthewj on October 13, 2020 at 18:53:52
The reason is plain curiosity;), honestly I have too much free time on my hands these days...
Seriously though, I'm just really curious about the Soviet stuff. The tubes of my BAT are mostly Soviet-made or semi-Soviet, so I decided to swap the modern ones with NOS.
I found a guy in Russia, who knows his stuff, he also is an avid DIY-er. He promised to find whatever I want. So far, I have had a really unbelievable experience with the Soviet 6J9P-E tube in one of my preamps, from their first tube factory, and it killed literally every 6688 tube I've ever tried.
Don't remember what's inside my amp (probably new Sovteks), those 6922s are in the bottom of the amp, I have to remove the panel to see it. Once I have the replacements, I'll report my findings about them.
Just as an aside, I had a strong preference for the Voskhod 6n23's.
Your taste in tone may be different, but I preferred the Voskhod in a Counterpoint preamp and as a buffer in a CD player. Reflektor made ones always sounded more sterile/hard to me than the Rockets.
The Tube Store is calling that one "the equivalent to the 6DJ8"?
Oops. On edit: that is "Tubes store.com" that is referring to it as such.
(The Voskhod, that is.)
The Tubestore.com (which evidently is a different store) is saying:
"The NOS 6H23P-EB (Premium) tube is a very noticeable upgrade over the Sovtek 6922 tube and Electro Harmonix 6922 tube. They are incredibly durable and can handle the punishment of modern pre-amps, including those made by Audible Illusions. They excel in detail, speed, and soundstage. The highs have air and sound natural."
Big difference, also, between the prices of the Voskhod at Tubes Store.com & the 6H23 at The Tubestore.com.
