Original Telefunken boxes. No diamond on base of tube. Similar mesh plates to Mullard/Amperex.
NOS labeled and boxed as Telefunken. Great sounding tube for Matchless, Bad Cat, Dr Z, Vox or any guitar amp application. These have very good microphonic performance but "Lowest Microphonics" version is recommended for combo amps.
NOS in good original boxes. Labeled and boxed as Amperex or Philips. Excellent tone and tested for microphonics in a Vox AC15.
I believe this is the earliest version of the Mullard. VERY cool tone in every way. Hi Mike, The Mullard long mesh plate came.... the best of all of them... sounds absolutely fantastic, great OD, great headroom too.... I want to work on stocking up on these, what is your stock like on the Mullard Long Mesh plate EF86s... I love this tube so much I want to save up and get another as soon as I can, and work toward more over time.... I am also going to send an email to Mike Koski at Xits with a link to this tube and let him know about the sound...
Original and white boxes.
