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.
Tube rolling in Yaqin Pacific Valve Tube Buffer
A Shuguang 6N1 is included with the tube buffer from the factory. It sounds pleasant. An Amperex 6dj8 orange globe A frame I tried, sounded surprisingly thin and the highs shrill. I can only guess that the buffer is "voiced" for the supplied Shuguang 6N1 tube and NOS tubes therefore don't sound as one would expect.
I read that owners of Yaqin & Pacific Valve tube buffers have bee using JAN Philip green label 6922.
Does anybody have any other experience with tube upgrades for these tube buffers?
Thanks.
