Z TUBE (#230821574748) The Neumann U67 Tube Microphone and VOX AC15 Amp is just one application for EF86 tubes! "... Dear Tube Musem, Hi! Just wanted to let you know that I left you a positive feedback this eve and was hoping that you would do the same.In the case of this transaction feedback doesn't cover it! I want to thank you for turning me on to the info on tubes in general, but this EF86 specifically. I couldn't be happier or more blown away by the performance of this tube. I put it in my 50th anniversary, handwired Vox AC30H2 and bam-o!! The volume and headroom increase was phenominal. I can't measure the db's but it is amazing. But the tone and the articulation is something to be heard, and heard, and heard...you get the idea. Whether it's a guitar with humbuckers or a Strat or Telecaster, the amp now has such personality I'll never let it go! I'm really just stunned, hence my rambling on to you in this email! So, I'll say thank you once again and you've got my email and my eBay call sign. Please get in touch with me when you get some unusual, cool tubes, much like this EF86. I'm out of charactors,thx again! EF86 6267 VALVO for U67 - VOX AC 15 AC15H1TV - VOX AC30H (2007) Heritage series 50th anniversary models The Heritage series 50th anniversary models incorporate the classic EF86 pre-amp tube , which although subject to failure in the late 50's had been re-introduced and improved. The classic VALVO EF86 pre-amp tube is remarkable for its high gain and for the notable harmonic overtones it produces and feeds to the power tubes when driven into distortion, providing the creamy distinctive VOX sound of the early hand made amplifiers produced by Jennings of Dartford. Clapton, Cream, Pink Floyd and Queen are ambassadors to the success of the early AC30's. The Heritage series 50th anniversary model with the EF86 tube stands alone as either the AC15 or AC30 with this distinct circuitry not found in the current VOX line-up. - DR.
