Russian Tube Preamp, No Return, Here I go again

Elliot, you need not fret about the availability or lack of 6N23 tubes in the US or the shipping expense from Russia. I’m sure there are some very suitable substitutes that are readily available here. Moreover you have thousands of hours of listening ahead of you before you even have to solve this non-problem. That’s assuming you like the SQ of the Russian preamp. If you don’t, you’ll be selling it before the tubes wear out.

Did some research for you. 6DJ8/6922 are equivalents. This is a whole family of tubes sold under different alphanumeric designations. You could hardly have a wider choice. Go to Tubes Store for example. Oy.

lewm,

thanks for looking this up, very helpful.

I agree, thousands of hours, and, my office system gets less work than the main system. On the other hand, it could arrive smashed.

It was a 'what if?' and, my recent lousy sounding 6SL7's for my Cayin is a warning about spending money for the wrong substitute. I got lucky, my 2nd choice was a winner.

If it sounds great, a direct replacement may avoid a tube chase.

6N23 = 6922, etc. They are the same tube so far as I can tell.

lewm,

thanks as usual for your help.

any thoughts on using these adapters?

just curious, I am not sure 6sn7 would fit in/thru the case.
