has any one used this EF806 from eurotubes?
Quote from the site:
The JJ EF806 is a premium version of an EF86 and we could not be happier with its tone and performance! I have been asking JJ for this tube for years now and have always stressed the fact that microphonics must be very low. Well they have pulled thru again! Its quieter than any of my NOS EF86’s and the construction is almost identical to the Telefunken EF86 and it has the same sweet open sound!

It seems a good choice to try on the DC30. Anybody?

Lovely amp, the best...
Right now I use the EF86 channel, at 15 watts (enough to cover small clubs wich is most where I play) with volume not past 9 0'clock. I use this chain

guitar->
535q wah->
Retrocomp compressor (build by RO Tiree on Gnet)->
SD/808 Analogman SD1-> (as main gain, volume and gain 2pm)
DS1/PRO Analogman (gain almost 0, as a booster for solos)
Maxton Volume pedal->
EF86 Channel

Effects loop:
GE7 eq to add some brilliance, my EF86 channel at low volume is too bassy, so the eq help to cut trough the mix.
LS1 Line Selector, wich engages or disengages:
Yamaha ch mII chorus
Eventide TimeFactor

This way this amp is the most versatile I've ever played. I can go from chimey cleans to crunch or high gain sounds, just combining 2 dirt pedals. Every single sound is amazing, other guys with brand amps haven't been able to pair this sound.
I use it with a 2x12 custom with V30 and G12H30, or with a Marshall 1960A. Both cabs love the amp, each with it's own characteristics.
As somebody on the forum said, this amp forces you to be a better player, it really reproduces every single stuff you do (for bad or for good).

Well, my first set of JJ's were faulty from the start, but I had asked Nik to include an spare set, so I just replaced them and nothing wrong happened, but the amp came alive. So at that point, I ordered another set from www. eurotubes.com as a new spare set.  I have not test it, I will test it to make sure they're not faulty.

Another thing you can do is to swap the two outer tubes by the two inner tubes, and test the amp on lo power/hi power. If I remember well, this option "cuts out" the two outer tubes on 15 watt setting (you can verify this by looking at the tubes as they go off when you change the power switch).

What is funny is that if your problem is related to powertubes, both channels should be affected, not only the EF86 I believe. That's why I was asking about the EF86 tube...

I'm not tech at all, but as long as I know there is no need to bias this amp, you just use a matched quad of powertubes (I have already changed my powertubes once, and it only improved the sound!). The EF86 tube is prone to be microphonic, this was my first questión to Nik about the rubber ring that came with that valve.  Did you try another EF86 instead the one you replaced?

woow... how could I miss this forum all of this time... Salutes to Nik from Walter from Costa Rica!

here are a couple of links from a gig we had, bad camera recording but shows how the DC30 (amp of amps!)  gets along with my pedalboard.... (sorry for the sloppy playing  )


(nice solo at the end!)

This is all played through the EF86 channel at clean setting 15 watts, using Analogman SD-1/808 and DS1/pro to get gain sounds, a Yamaha CH-MII chorus and a EventideTimeFactor delay... to custom 2x12 with v30 and G12h30
