Default RL12P35 amplifier

Hello oldeurope

I can see You have a SE output amplifier based on RL12T15 tubes.

Do You have any expirence with RL12P35 tubes. I have a lot of them, and want to build a 5 canal amplifier with them.

Regards

Benny

@oldeurope:

I'm also interested in any data regarding RL12P35 in triode connection;
I have several Wermacht Telefunkens , and few sockets .....

one unknown factor ( curves for triode operation I can measure by my self ) is max schirmgitter voltage .

can you share your experience ?

btw - I like that picture of old and ugly triode

Ups, I misunderstood.
you asked for the RL12P35 because I made an RL12T15
amp? Very confused...



Sorry I can not help you.

Hey oldeurope

This is Ok

The reason I asked is, I know there is a lot of RL12P35 laying around.

I want a schematic with a SE amplifier with this tube.

Regards

Benny

Smile About RL12/ P35

Hi! Hojvaelde.
Depends on your post, you said that you have quite a few of the tube RL12/ P35. May I buy some from you? TKS!

i'm also interested in getting hold of a schematic for RL12P35, i have a few Philips PE08/40 that is the same tube.

Here are some short data that i have 'bout the RL12P35 (TFK)

Max shirmgitterspannung ist 200V
Schirmgitterverlustleistung 5W
Kathodenstrom 150mA
Anodenverlustleistung 30W

Heizung 12,6V und 630mA typisch

I would guess that a current around 90-100mA and 300V on the anode would be great?
I will try to scan the "kennlinien"...

BTW, these tubes will need a bit of "oomph" to be sufficiently driven, perhaps a 6SN7 would do the job, otherwise maybe a three-stage rocket with ECL82/86?
