Just purchased one of these off a popular auction site. I have a CD player acquisition "problem". Photos from the ad:

Given the age of the player, I'm excited at what appears to be the almost mint condition it's in. I'll post up some photos of my own once it arrives. Apparently these are pretty rare, with only 7,000 units made according to one site I read.

Anyone have any suggestions/recommendations for "6922-style" tubes to roll in it?

    $300 per pair, eh? That's more than I just paid for the player, haha!

    I just got a message from the seller that said he's going to throw in an extra 2 "JAN 6922" tubes for me. I think he means these: https://www.tubedepot.com/products/6922-jan-philips

    You can also hit up some of the Tube Guru's here. They may have something that fits your budget.

    JAN just means joint army navy many tube makers made jan tubes.
    Look into brent jesse i was just giving a reference. Brent has many tubes priced low to high.

    Thanks Ivan. I guess it's a mystery then to which JAN tubes he's sending. I'll have to wait and see.

    Once I get it and verify basic functionality, I'll give Brent a call and talk tubes. :)

    To be fair i have bought tubes for my tube buffer that cost many times the price of the buffer itself.

    Nice! Do you think the $350 upsampler board is worth it over the standard setup?

    Not very familiar with that paticular unit, but, I'm thinking it's going to be a nice piece to play with. Get it up and running and give it some time as is and then reassess. Get a good baseline before starting the tube rolling. If tube rolling doesn't get you where you want to be, well, start ripping the innards out! Seriously though, I'd give it some time before considering upgrades as they may not be needed.

    Looking forward to your take on it.

    Well it arrived today so I got it unboxed and it's playing currently. Seems to work just fine. I took a bunch of photos of the player and the extra tubes that were included. Looks to be in pretty good condition for it's age!

    I was trying to identify what tubes were installed in it. It looks like they say "Gold Lion" or something in cursive yellow writing, and say W GERMANY. I tried to remove one so I could get a better photo of the cursive writing, but it promptly wiped right off on my finger in the process. Der duh der.

    Why does it have more capacitors than a lot of receivers have? Man, that's a lot of power storage!!

    Don't skimp on the tubes. Those are mediocre tubes. I woudn't walk across the street to get those Jan Philips tubes, for free.

    Drew,

    Andy @ Vintage Tube Services shows the Matsushita 6DJ8 tubes on his "Stock list." I had a set of these from him in the past and they do sound very good, especially at their price point. The stock list is not up to date so the inventory or the prices may have changed but it doesn't hurt to call and chat with Andy; he really knows his stuff.

    What was your next move after this CDP? Was it a CDP + DAC or did you go with a different tube CDP? I cannot recall.

    These players enjoyed near "legendary" status in their day. Enjoy.

    My guess is --
    That's a space effective way to get appropriate capacitance for HV (relative to soiled state) DC in a small (at least vertically) space. SS working voltages are typically pretty low -- even small-signal tubes (like the 6922 in the piece in question) will require fairly high plate voltages for best results.

    It was a worthwhile upgrade IMO. Really helped the midrange. The 'New Tube' design was a successful attempt at a more analog sounding CD player.

    IIRC a ModWright Sony 999ES with tube output, then a ModWright 9100ES with tube output. After that it was DIY. A single, then dual mono, Twisted Pear Buffalo III ESS9018 DAC with discrete balanced out. It still sounds very, very good.

    Hard to tell based on the photo's. I only know a little about the 6DJ8/6922/7308 tubes. Never had gear that ran those, so never really bothered to learn much beyond the basics.

    The yellow label tubes appear to be "A" frames which means it's mostly likely a Dutch Philips made tube (not the same Philips as the blue label ECG's). I see made in Germany and possibly a set of grayish acid codes???

    The blue label ECG's most likely made in the mid 80's aren't that terrible unless you compare to the 60's tubes. So my statement was a bit over the top for emphasis. If your serious about getting tube experience the ECG's simply won't do.

    The better 6DJ8/6922's are a bit pricey. These were never intended for audio. They were adapted for audio use later on, mostly in pre-amps. The first 6DJ8 wasn't even produced until 1957 by Dutch Philips strictly as UHF/VHF component. Later found to be excellent used in oscilloscopes.

    Why do you not answer my question and also at the same time post a picture of something (what the heck is it? Is it an integrated amp? ) that's not a CD player to compare with your Cd player?

    Thank you, @mhardy6647 for trying to explain the reason for those multitude of capacitors being in a CD player. I can relate since Cd players that don't have a tube or tubes don't have 1/10 of them, I don't think.
