One platinum matched pair (2 tubes) of rare 6GB8 6G-B8 Toshiba Japan Hi-Fi audio tubes, Tokyo Shibaura.
They are tested with 250V on plates and G2 and -12V on G1, 100% for NOS tube is 75mA, the results are:
Tube No1:79mA
Tube No2:83mA
They come without original boxes, I've got these tubes in a bundle of more than 1000 tubes I've bought 20 years ago. I can't say if they are NOS or not, but according to test results and visual appearance of the tubes they look NOS to me and I'm sure they will work for years in any 6GB8 hi end amplifier.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.
Size: AF997
This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
