Matched Pair 7-Pin GE JAN 5654W Vacuum Tubes Upgrade for 6AK5/6J1/6Ж1/ EF95/6J1P

I bought the douk phono preamp, and it had an annoying buzz. Replacing the tubes with these was perfect and my setup is finally quiet!

package came in as advertised -thank you

Much better replacement for cheap Chinese tubes that came with my amplifier. Warmer sound.

Edit: After about a month, these balanced out, so I bumped the rating up to four stars. Still annoying to deal with while they were breaking in, though.I bought these after a tube in my amp broke while moving. They work, but seem poorly matched--one of my channels is noticeably louder than the other now. I was able to fix this by adjusting the balance on my amp, but I don't think that should be necessary.

I listened to the DOUK Audio Headphone amp with the included 6A2 Chinesium tubes...Sound seemed ok but had weak bass and thin midrange. Replaced these with the GE NOS JAN 5654W tubes. These GE tubes opened the soundstage, made it fuller and enhanced the Bass and Midrange audio response. Use the GE tubes, throw the Chinesium tubes in the trash...

The media could not be loaded. I've AB tested these against the non military GE version (no W), it's night and day instant difference. Less hiss (none more like it) and louder

I have the XDUOO MT-602 amp paired with Thieaudio Ghost. These sound great. I had Riverstone tubes for a year they are awesome. So I figured I'd give this brand a shot. $20 bucks a year to make to music better is fantastic.

They can be the best quality possibly for longevity but sound quality was way worse after installing into my Douk st-01 pro. The sound was flatter than flat. I put back the stock tubes and the sound was night a day. Stock tubes were super crispy with a nice punch. These were almost to the point of being muffled. 3 stars because they do work as far as changing sound.
