Many Thanks! for this intel. Hopefully, some day, I will own an AA cd player.

I have 3 AA players (capitole )
I have tried all tubes i could found ..raytheon from tubeworld is one of the best you can buy today but i think gryo treatment is making a trick at the sound (i am not sure but its not so normal sound is very clear but i think ...too bright and overdubbing ?? ) whatever ...
i have a box 6n1b and like you i wish i could try them but
its not so simple ...wires is very near and very complex to find where each one goes (its not clear like 6021 there is no mark or space ..to get start there is no front and back !! )
The best tube i try in he past was a westinghouse black plate and GE 5 stars white letters but both not possible to find anymore ?
I think russians tubes is a must to try (6n1p/6922similar i use in my s.e amp is a very good tube -if you find a good pair- and kills many tubes cost a fortune )
Anyway if you have the experience with AA player let us know ..it may be very interesting !
Finally i found the time and try the russians 6n16b
i found there is a mark at bottom glass that shows the plates (8&5) so was easy to make the wiring ..i did not noticed that before .(not easy to see anyway )
..well it seems or i did something wrong or this tube make capitole sound like ipod !!
I must say i tried the tubes also to prima amp and prima cd -before use it to capitole- ..in all cases was dissapointing
At first you think the sound is interesting ..but soon is obvious it is just "nice sound" music is not there !!
compare to raytheon it is like a bad joke !!
The heater is quite more (100-140ma more than 6021)i dont know if this is a problem for the power supply.. but i dont think so..
Anyway i did the tube rolling and i use differnt systems ...to make a long story short ..the tube for sure is not made for audio!!!
No need to say i check power supply voltages etc ..all tubes was ok (capitole has 5,9-6v for filament lower than typical but thats ok ..or maybe is better?)
It is really mysterious ...so bad tube !
I really wonder.....if the extra current tubes need is too much for the player supply!! or something else that only russians knows !!
First think that the tubes 6021wa and 6111wa have an expected lifetime of
about 10000 hrswhen we started with these miniature tubes I proposed to use the 6111wa which has less gain and comes close to this russian 6n16b
replacing the 6021 by a 6111 is easy as they have exactly the same shape.
this might be a better proposition then that funny brother PUTIN-tube.

If you tried the 6N16B-V in the AA and you didn't like them all I can say for sure is that it's not the tubes fault.
You cannot "drop" the 6N16B in a circuit designed for the 6021 and expect to work wonders just because they are both subminiature, the two tubes have very different curves.
Biased at ~7mA and with 100V anode-to-cathode the MELZ 6N16B-V is the best kept secret in tube audio and one the best sounding tubes EVER MADE comparable only with BENDIX or diamond TELEFUNKEN.
AA was just bought out by Vermeer Audio of France. CDP's are no longer made from the website but they have taken the circuit of the Lafontaine and LaSource and supposedly improved the power supplies on the offered DAC/SERVERS. An upgrade will be offered to all of those owning the latest players mentioned above. I am not sure about Capitoles/Prestiges. I was lucky enough to buy a used Lafontaine with Esoteric transport and it is wonderful....the best I have ever heard in my system.
I was able to hear it compared to a Lampizator Big 7 with 45 tubes last weekend and I thought the AA was better although be it with a different PC and cables so not exactly a true comparison.
I own some 6021W's as GE 5 Stars, Sylvania Gold Plate, Jan's, Thomsen France (Made in France), Heintz & Kaufmans. I don't have the guts to try other tubes at this point outside the circuit design.
Issues can be resolved by Sedonix in Sedona, AZ. Speak to Greg as he said he can source parts from France. He has not worked on any of the later players thank god for that. The latest players are truly source winning wonders and appear to be much better in build quality coming from an owner of past Capitole/Prestige owner history background. One caveat, I doubt there is many of them out there.
