I’ve been reading this thread with interest. By chance, a few weeks ago I won a nice pair of NOS CBS 5692 red base tubes at a very good price. They have now replaced my much-enjoyed pair of Ken-Rad VT231. The CBS 5692s do not seem to be as sought after as the CBS/Hytron tubes. What I can say is that these tubes are very well balanced and the quietest of any 6SN7s I own. |
I'm not enjoying my second pair of 1578's at all. It's taking a long time to burn-in; they don't have the bass extension and impact of my first pair which sounded great from the start. It's a shame one of them crapped out. My news of the day is very positive. The replacement 1578's sound incredible after 30 minutes warmup. A low noise floor is revealing subtle sounds from a deep 3D soundstage. Fingers crossed on these tubes. My first pair sounded great until 50 hours when they started to crackle and burn. Tracking shows my Melz 6N8S from Ukraine has passed through JFK customs. Something to look forward to. |
Dear @lowrider57 and @shkong78 - might you be able to post pictures of your favorite Melz 1578 tubes and also the name of your trusted ebay sellers? From my research (much of which took place before this shootout thread was started) the desireable Russian 6N8S/1578 tubes are the ones with multiple round holes up and down the plates, the OTK stamp and (ideally) 1578 stamped on the tube. Now on ebay I am seeing several other variants being marketed as 1578s. One is a more common one without the multiple round holes up and down the plates. This one looks a lot like the Foton 6N8S, which is pretty common. Another has the round holes, but no OTK stamp and no 1578 stamp. Which ones are you guys enjoying? And how are you able to confirm the production dates? BTW, some of the Foton 6N8S tubes sound very good, but some sound rather thin, in my system. Thanks, in advance, for any info you can share.
