@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

confused
Ups, I misunderstood.
you asked for the RL12P35 because I made an RL12T15
amp? Very confused...
Sorry I can not help you.

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?

You can buy the tubes on www.ebay.com, use the search function.
But the base, it will be difficult.
I have seen 3 pieces i my life and I have one on stock.
The price is at least two to three times as high as the tube price.
I had fabricated some of POM or other plastic material.
