These are 6V6GT's even though they say 6V6EH. GT stands for "glass tube" and these should work fine if your amp calls for a glass 6V6 tube.

Will these work in my yaqin cd3 6n8p stereo tube audio upgrade tube buffer processor?

No, the 6N8P is not compatible with the 6V6GT.

Product Reviews
Terrific Electro-Harmonix tube. Been waiting a while for it to come back into stock for my 1967 Fender Deluxe Reverb...but Antique Electronic Supply got it to me fast. Good job!
Happy with the tubes in a 5E3 Deluxe scratch-built chassis. Good price for a matched pair. Thanks much.

Tubes were packaged well. They worked when installed.
The 6V6 EH sounds great in my Egnater amp.
Not what I was hoping for? I’ve used these once before and sort of liked them. I bought a new set of Tungsols before theses and something must have been in my signal chain that made me think the tubes were distorting too early so I bought these to try instead. When I compared side by side, clearly the Tungsols were the clear winner. More headroom, more high end and louder and sweeter overall. I’m sending the EHs back. Spend a bit more and get the Tungsol 6V6GTs. They’re 5 star tubes imo.
I installed this tube in a 5F1 circuit. The tube red plated immediately. I had to go back to the Tung- Sol.
Timely shipping, my amp sounds great now!
These tubes perform perfectly in a push-pull hi-fi amp (an old Pilot 1030). The Pilot amps were little known, but on a par with the best high-end equipment in the 1950's. After re-capping the filter caps with F&T electrolytics (the best I've ever used in 45+ years), I attempted to match the many 6v6 tubes I have in my inventory. Nothing came close enough, so I ordered these Russian tubes as a matched pair. I was amazed how well they work together! I generally check out amps by monitoring the applied input sine-wave signal and the speaker output signal on a dual-trace scope, and comparing the waveforms. My best-matched pairs had a "glitch" at various frequencies, but these Russian tubes were dead-nuts-on from 15 hz to over 30 hz. (The Pilot amp is of excellent design, and the output transformer handled this frequency range with nearly flat response.) I am impressed. Don't even bother with "NOS" tubes; IMHO these are as good as they get.
Great tubes.I recommend it.
Antique electronic has good price transformer.
Thanks.
