RL12P35 amplifier

[Hojvaelde]

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

Hello,
yes, I have experience with this triodes.
TeKaDe or Telefunken?

Kind regards,
Darius 🙂

@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

Hey oldeurope

RL12P35 is pentodes

[oldeurope]

confused

Hey oldeurope

RL12P35 is pentodes

Benny

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.

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!

 

[Mr. Triatic]

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?

Hi all,
I am looking for 2 pcs of RL12P35 tube socket?anyone can offer me?or where can i buy them?

 

[Hojvaelde]

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.

Hi Benny,
I got the tubes but without the base socket!why is so difficult to get the socket?
is it because the sockets were made very few in those days,but i believe some german or dutch they have them on hands!

These people maybe?
