Hey

I had for 2 years ago build 2 small SE amplifiers based on EL34 (Design Tom Schlangen).

Now. I want to build 3 more for a 5.1 amplifier. This is no problem.

My problem is, I want to replace the EL34 with RL12P35 tubes (have 20 on stock).

I have problems understanding the Germans datasheets.
I understand the G2 voltage is max 200V but what is G1 voltage when b+ is 425 to 450 voltage and the anode current is 50 mA.

Can any help me???

Regards

Benny
