ecl86&ecc85 scheme

[mad_z]

As a christmas gift I got ECL86 and output tranny from vintage radio + ECC85. I know I can have some 2watt mono amp based on ecl86 but have no experience in tube amps. Tubes are in a very good condition.
Maybe someone of You have some simple&good scheme for SE using this tube???

Any hints?

You can also look for schematics that uses ECL82, that is pretty much the same tube (I THINK!!)

ECL86

Well...not really.

The ECL86/6GW8 is a triode+penthode containing 1/2 of the ECC83/12AX7A + an EL84/6BQ5.

Knowing that,it would be more interesting to look for circuits using exactly those tubes.

So the ECC83 can be used as an input amplifying stage and the EL84 as output tube.

Obviuosly it can be used in SE or PP circuits.

Cheers,

what about topology on the attached picture???
i will look also for schemes for 1/2 of the ECC83/12AX7A + and EL84/6BQ5.

Thanks!

Fuling - thanks for links - I'm viewing them now...

FINE BY ME

Hi,

Sure,you can base your circuit around that.

I also recall the Revox G36 using that tube in its output.

You can have a look here:

PP AMP

Hi,

Here's one if you want more power:

okay. so far I have found few solutions on the web, but the most appealing to me is the one below - any comments, hints?
fdegrove - Thanks for links!

At the moment I'm going to stick to SE topology. The goal is not much power so why not))

Well,I can give you links to have a dozen more....

This circuit looks like something the guy did for his own fun,adding the EM80,a 10K volume pot,too many adjustable working points to my taste.

At least there is a usable link for the OPT and if it suits your needs as well,why not after all.

Cheers,
