These are Mazda EF86 valves in their original boxes and show all the distinctive characteristics of the high quality Russian EF86’s made up till the 1980’s.They have the typical little dimple on the top of the glass that was so typical of Russian valves up till the early 1980’s. The valves are in their original boxes and are unused. The box says “foreign ” as does the valve. These valves are reported to sound really nice and are a good upgrade for early Vox amps.
We have fully tested each valve for you and give a 120 day warranty.
Each valve is tested for anode current and Gm ( both are shown on our stickers on the box)
"Prompt delivery, boxed and secure, included a tip sheet and a handwritten thank you. All valve sellers should be like this. Highly recommended." - Steven L.
"I don’t think I’m the only guitarist out there who knows his/her guitars, but very little about tube amps. I ordered a Supro valve kit (which is great), but it’s the service, help & advice I received from Stewart that was outstanding. I was going to say ‘these guys’, but it didn’t seem right, as my communication was just with him. Thank you!" - Robert G.
