Product Reviews
Needed this tube to build a vox ac 15. Sounds great fast delivery.
Fabulous sounding tube, modded my super reverb normal channel with this EF86 (VOX emulation). Couldn't be happier, breaks up nice and has that typical mid hump VOX character tone. Makes the super very versatile and gives purpose to the always unused Norm channel lol
just did a mod on my Super reverb amp converting the Normal channel into an old VOX preamp using Tis EF86 pentode. It sings, just loving it!!
