Outer foil k40y-9

12dodeca · 18th February 2009, 12:48 AM

Does anyone know which side of a k40y-9 is the outer shield? I read that the backward E indicates this, but it's been awhile and I forgot.
Tried google but after an hour I give up. I don't own a scope so that method won't work for me. Richard

This is my understanding. I'm hoping someone will correct me if I am wrong.

Is this really necessary? I have just built a linestage and the final output caps are audionote foil, I was on the website earlier and it appears that i have installed them the wrong way round! beginners luck!! my question is... will i really notice if i turn them around?

cheers stuart

Auricap says the outer foil should go to the signal source (driver stage) and the inner foil goes to the circuit output (power tube's grid). Many people who have tried say it doesn't make much difference either way.

If you ground the shield it does not matter, but if not it may pick up lower frequencies a bit better when outer shield is soldered to a grid.

In any experiment any result is the result. Even if it is negative.
