Tube rollin' for CD player?

[HarryO]

I just picked up a Sheng Ya/Vincent CD HDCD player and I've been swapping out tubes trying to get the max sound. Anyone been playing with this set up got any tried and true suggestions? Right now I'm running Amperex Bugle Boy 12AX7 ECC83 and a Gold pin Siemens 6922 6DJ8. This thing sounds great and the front window tube glow is a nice cool feature. I'm just looking for "More" from my tubes. I'm short on the 6922 6DJ8 stock and wouldn't like to keep adding to my personal collection of unused "back up" tubes.

Thanks,

HarryO

I'll give you a good price on some new Sylvania 6DJ8's new and I have 10 from the same lot number. You could call the CD manufacturer and get their recommendation on best tubes for that unit. Who would know better?

Thank you on the offer. I'll keep it handy.

I am hoping someone on the forum here has tried different types out and found a nice match up before I spend any more on tubes that just end up being back ups. I have the original Philips tubes, Amperex, Mazda (England) and a couple of Diamond top smooth plates now. Just looking for a short cut to.

There is quite a bit out there that can be used in place of the 12ax7.  A lot of folks like the 5751.  If you have any of the lower MU tubes, it's worth a try in place of the 12ax7.

SF,

Thanks for the options. I've got a couple hundred tubes to play with and I give them each at least an hour of warmup/playout. i'm hoping to find someone that's done a bit of the legwork already. Don't get me wrong, playing with this stuff is a big part of the appeal to tubes but there's not enough hours to the day sometimes.

I tried to send you pics of my newest amp and the emails kicked back to me. I'd post some pics here but I keep getting an "OOPS ERROR" when I try to upload them to the forum. I'm about ready to give up. I know as much about cameras as I do ladies fashion. NADA, zip, nyet. nuttin'.

Tx again,

HarryO

SF,

The 6922/6dj8 is used as the output tube on this. The 12AX7 ECC83 affect is minimal. Nice conversion from digital to analog on this. Philips carriage. Well made units. Cool looking inside and out.
