Jan 01, 2016 · Holy dynamic swings Batman! The JJ is a fabulous tube: powerful with tons of headroom. Great with hard rock, great with Chris Squire’s bass. Wonderful with classical, conveying a great sense of air and soundstage. JJ could easily double the price of these fine tubes–they’re worth it, and then some. Can't find it here?

We test each JJ EL34 Pentode valve on our analogue and digital testers This ensures that we catch not only poor quality new valves but in the case of vintage valves we can detect and reject the worn ones. Here is a summary of the tests. Heater filament test, short circuit JJ KT88's are killer but you have to bias them VERY hot to get full power; they can take it, but they get hotter than the others. I'd LOVE for someone to do an impartial trial, because I think my favorites also depend heavily on my tonal preferences and proclivity for insane volume."I'm just the fly in the ointment, the monkey in the wrench ... Normally, I like JJ tubes and have used them in a number of projects, but to my ears, the JJ EF86 sounds weak in this particular project (I tried two different ones). One last thing: this amp is *not* a clone of the Dr. Z Route 66. The Route 66 uses a single EF86 into a passive EQ section, to a phase inverter and a fixed-biased KT66 push-pull pair.

The JJ Electronic EF806S is a high quality reproduction of the classic EF86. This pentode features a robust construction with the internal shielding used in the original tubes. The JJ EF806 can be used in any EF86 circuit including microphones and amplifiers. The Vox side (ef86) has more range top to bottom, and less low mids. It will grind in a very cool way as well. I love the EF86 for the clean/dirty tones. The 12ax7 for the Grind. Both seem to clean up beautifully, but the EF side will do it better. There is a lot of upper mids/highs with a strat and the EF86 side. "Chime and Swirl" is what it is. 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. With only 12% space volume, 70% heater power and 4 to 3.8 watts output power against the ECL11, the ECL86 represents the final perfection of this kind of tubes. Those AF-multiple-tubes were asked for again, as FM-detectors became fitted with Ge-diodes, making the EABC80 obsolete.
