Today is the third day restoration
----------------------------------------

I think I have solved the red plate problem.
If you owns a 12.1 you will see there is one ELECTROLYTIC capacitors 25uF next to each coupling 0.25uF.

I was so stupid I have overlooked the circuit I did not wire the PIN 3 of both el84. That means one of the el84 was not given a 100uF ELECTROLYTIC, making an abnormal glow in the plate :-)

Sorry I cannot express myself well.

I have to say thanks to Richard and DD for their giving hands during the restoration :-)

What's the sound of my Gold Pilot? It sounds nice as an el84 tube amplifier should be, especially the female vocal. My ears were too sensitive to el84 before. However, after my ears turn bad, I am able to stand the el84 for more time.

An el84 amplifier really sings with LS3/5A :-)

----------------------------------------------

CP

Thanks for the kind words.
There is still a long road to go. I have to buy a quad of 0.1uF coupling capacitors as one of the them was still leaking 1.2V. And I have to fine tune the amplifier. I hope it can attend the el84 party :-)

BTW, can you bring your Germany el84 to my place? We can have a small scale el84 party :-)
I will be off this Wednesday & Thursday :-)

Special Stereo 20??
--------------------------------

Hi STEVE,

thank you for your reply.

How I can see from your BIC advertise picture and from my advertise, the Leak
Stereo 20 has just a black screen logo, the early LEAK logo.

It meants that the Stereo 20 has champagne finish.

These amps whithout doubt were imported from USA Leak agent and from Italian
Leak agent and perhaps from other agents out of UK around 1960/1961.

I can access to Italian magazine on 1961 issue.
I will to know you the next week.

Best whishes,

PIER PAOLO - ITALY

Better not mixing power amp with integrated amp or then we have to test all combination of pre-amp as well.

John - didn't you also have a Fisher SA-100 and a Eico HF-86?

For the EL84 Shoot-out, we have among us at least the following :

Stereo EL84 PP power amp :

- Leak ST20
- Dynaco ST35
- Pilot SA232
- Fisher SA100
- Arcosound 20-20
- Eico HF86

Mono-block EL84 PP power amp :

- Leak TL12+
- Stern Mullard 5-10
- Heathkit MA-12
- Verdik Q-10
- TFK V81
- Klangfilm V410
- Fisher 30A
- Eico HF-14

As it is quite impossible to test all 14 amps in one party, so we should have some preliminary rounds as suggested by Gingers.

Anyone got other interesting EL84 amp to join?

Yes. I have them. I think too many el84 amplifier will confuse our ears :-)

------------------------------------------

But SA-100 is supposedly to be perfect match for the Fisher 400CX-2 wo!

I think CP only have the German Klangfilm V410. So which EL84 amp you got you think will be the best defender(s) of the home ground?

The SA-100 bias adjustment can be tricky. The amp was designed for 7189. But NOS EL84 should also work unless the bias set too high.

And different 7189/EL84 probably have different sweet spots in term of bias.
