It's mine preamp
oh, i've noticed that (nice work by the way )
i'm talking about the tubes, who makes them today or where they can be obtained?
Sorry, my english isn't perfect I think, manufacture is stopped. It is possible to buy this tubes NOS only.i'm talking about the tubes, who makes them today or where they can be obtained?
soundbrigade said:6E5P (6-5) is a tetrode that appears to have high gain and low Z (can actually works on it's own as headphone or small amp).
do you have a link to a spec. sheet? i could not find anything... i'm mainly looking for gain
You have a pdf http://www.pastisch.se/faktiskt/6e5P.pdf .
It's in Russian but if actually you live in the country indicated with your flag, you should have some Russian neigbors that could translate the text for you..... well it's bilingual. Missed that.

What's to gain??!! Women, free drinks, Mercedes cars ...
Here I have something for you.
A standard cascode looks as follows:
Anode voltage 100V, screen grid 110V and bias -1,5V.
Connect anode to B+ through R=6,8 ... 8,2K, screengrid to B+ through R=36 ... 39K.
This gives: u = 200, S = 30mA/V and Ri = 8 kohm.
Trioded: u = 30 ... 35, S = 30mA/V, Ri = 1,2Kohm.

The EF86 is a pentode that many current tube manufacturers make. You might want to look/ask around to get an idea of quality but JJ, EH, and Tung-sol all offer it.
