Tube rolling in Yaqin Pacific Valve Tube Buffer

I'm currently using Western Electric 6AK5 1940'S with great results, great improvement over stock chinese tubes. The unit with the tube upgrade alone sounds more cohesive with smoother top end. Consider doing some mods, it will transform this buffer. I have have replaced the output caps to Mundorf M-CAP Supreme Silver/Oil 1uf and removed the input capacitors now wired directly.

The unit I own is the Yaquin CD-2 which uses two 6j1.

I own the single tube version of the Yaqin and was one of the early advocates of the JAN6922 and it does work quite well. That said I have moved on to the Russian 6N1P with even better results. Cleaner mids, tighter bass and equal highs.
Incidentally the tube socket on my Yaqin is labeled with numerous tubes that can be used and the 6N1, 6922, and 6DJ8 are all included. Currently my buffer is in use between a Cayin MT12A amp and Denon multi format DVD/CD player to remove/smooth some of the harshness from the output and does so quite well.

I have heard many other people complaining abot the 6d orange so I think its just that tube.Try any 6922 or a JJ works just fine.

As one of the original posters of the Yaqin tube buffer using the JAN Phillips green label 6922, I have found using the 6H23 with the "Rocket" logo best the JAN Phillips. Better detail, imaging and depth over the JAN Phillips. You can find this tube very cheaply on eBay.
