HarryO Posted April 9, 2007 Share Posted April 9, 2007 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 Quote Link to comment Share on other sites More sharing options...
zuzu Posted April 9, 2007 Share Posted April 9, 2007 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? Quote Link to comment Share on other sites More sharing options...
HarryO Posted April 9, 2007 Author Share Posted April 9, 2007 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.

Guest " " Posted April 9, 2007 Share Posted April 9, 2007 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. tube mu 12AU7 17 * 4003 19 5963 19 5815 19 6189 19 ECC82 17 * 12AV7 41 5965 41 12AT7 60 * 12AZ7 60 CV4024 60 6201 6679 ECC81 60 * 5751 70 * 12AX7 100 * CV4004 100 7025 100 6681 100 ECC83 100 * Quote Link to comment Share on other sites More sharing options...
HarryO Posted April 9, 2007 Author Share Posted April 9, 2007 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 Quote Link to comment Share on other sites More sharing options...
HarryO Posted April 9, 2007 Author Share Posted April 9, 2007 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. Quote Link to comment Share on other sites More sharing options...
