From an Audiogon ad on the Voskhod Rockets (not mine) not to long ago:
:
"After an almost 3 year hiatus I've finally was able to locate 15 pairs of Voskhod 6H23n tubes that met my criteria of being NOS, manufactured in the Voskhod factory in Kaluga and having good lettering on the tubes. I got lucky this time because all 15 pairs ---{
11 pairs now, 4 pairs have already been sold}--- were manufactured in the same year and month!
These Voskhod "rocket logo" 6H23n tubes are the giant killers that have surpassed or equaled every tube they've been compared against in the 6DJ8/6922/7308/Cca genre of tubes. Maybe you’re skeptical of what I'm saying? Well perhaps you'd believe these two feedbacks I received from clients who previously purchased Voskhod "rocket logo" 6H23n from me? First is feedback left on July 30, 2010 by
wizeazz who said:
WOW! I was going to drop 400.00 for some Cca a buddy of mine had when I thought, what the heck its only 35.00. (
for these tubes) These things are the real deal. (
I) can't tell the difference between the two. Thanx so much Tom!
The second feedback is from
glitzenberger who left feedback on May 19, 2010 he said:
Tom is a great guy to do business with. I bought a pair of his 6H23 tubes and was blown away by the wonderful sound. If I had known how good these tubes sounded when I was looking for 6922 variants, I might not have purchased my Telefunken CCa's.
For many more responses in this same vein please read my Audiogon feedback. Oh did you know those Cca tubes they both spoke of are highly sought after and usually cost from $400 to $600 a pair when NOS? Yet both of these gents felt these $35 a pair Voskhod "rocket logo" 6H23n or ---{
6N23P if you prefer that designation}--- tubes equaled or almost equaled the sound of those $400+ a pair Telefunken Cca tubes!
Let me completely honest with you. I'm sure you'll find some expensive tubes in the 6DJ8/6922.7308/Cca genre of tubes that might have better highs, mids or even better bass ---{
I know I did when I compared a pair of Voskhods against over 100 different types of tubes in the 6DJ8/6922.7308/Cca genre of tubes}--- that said, what I don't believe you’ll find, is a pair of tubes that will sonically beat the Voskhod "rocket logo" 6H23n tubes when the sound is taken as a whole from deepest bass to the highest highs! Sure some of the more expensive $200+ tubes in this genre of tubes may sound almost as good or possibly even equal the Voskhod "rocket logo" 6H23n tube sonically, but none bested the Voskhods, with the one possible exception. A $450 pair of Telefunken Cca tubes. When I listened to the Cca vs 6N23P with friends from the Central Florida Audio Society, Space Coast Audio Society & SETriodes group the listeners were split as to which tube they preferred sonically. However everyone agreed when you factor in the cost difference of $35 vs $450. Purchasing the Voskhod "rocket logo" 6H23n tubes was a no-brainer!!!."
And these were for 1987s I think gray shields - he sold out at $35 an unmatched pr.
Got to try the Tele CCa!
