Audio Aero Capitole - 6021W subminiature tube ??


I would appreciate hearing from someone who can explain the performance of these tubes in the Capitole, including the typical life of the tubes, whether they are susceptible to becomming microphonic or noisy, and how to purchase or change them if necessary. I believe I read these are really small (like the diameter of a pencil) and that they are soldered onto the board. If that is true, is it then necessary to send the player back to the distributor or manufacturer if they need replaced, or are these readily available and set up for user installation? How many years is typical for the tubes to perform in the Capitole before replacement is necessary? Thanks.

I watched 'Globe Audio' change the tubes on my MKI a few years back.Even I was nervous just watching.
Not recommended that you try changing yourself.They are soldered in and you can fry the board in a second and then the tears.
FWIW.
Again, thanks for the responses. I own the Lector MkII and will soon have the MKIII board installed. I suspect it will retain the same sound with a bit more resolution. I have considered trying the Capitole primarily on the strength of all the positive owner comments, but as I do more research I wonder if that would be a lateral move from the Lector. I was curious about the Capitole tubes because it seems they must last a long time, which is a good thing for someone who doesn't particularly like dealing with tubes, but of course no tube rolling. I recently installed a pair of special NOS RCA triple mica 12AT7's in the Lector, and they are a noticable improvement over the stock tubes, which are also good to begin with. I don't particularly like dealing with tubes so what I would really like is an excellent solid state redbook player that does the same soundstaging and organic midrange thing as the Lector. I just don't know where to start looking at a reachable $3K or so price range.
Its not that difficult to solder in a pencil type tube with flying leads. You clip the leads of the existing tube near the glass. Then grab the lead with a tweaser, apply heat to the circuit board connection and remove each cut lead. Then just solder in the new tube.
I have owned the Capitole Mark ll and now the Prestige Reference with the cryoed tubes. The new cryoed tubes are expected to last up to 15000 hours or more even though the book still says 10000. Since these are run at a tricle the new cryoed could go way beyond even this. When I had my capitole and replaced the tubes with the new cryoed set (big change) I simply found an experienced audio repair technician in my area to replace mine that had a soldering station. With the unit delivered to them you simply retard any risk of shipping damage. It is really no big deal and Aero designed it this way to keep noise from the signal path developed by tube sockets.
I have had stock 6021Ws go out after three months in 3 differnt Prima CD players. In fairness, one channel or the other not both. Since the player mutes in "stop" position, you have to start a disc and then pause it to hear the noise.

The distributor is very hard to get a response from, even through a reputable dealer and the experience has really damped the otherwise nice sound this player produces. Clearly Audio Aero has purchased a bad batch of these but has yet to rectify the problem.

I have currently been waiting over three weeks for a response on my latest 6021 problem.
