Title: 6P1P wiring
Post by: Bieworm on May 09, 2023, 11:03:08 am

Hi guys

Quick question: on the tube chart of a SED =C= 6P1P-EV the anodes (pin 1 and 6) appear internally connected. I presume only one pin needs to be wired to the anode resistor? Or am I totally wrong and do I have to jumper both pins? Same for the cathodes (pin 3 and 8)  and the control grids (pin 2 and 9)

Thanks for your input. I think one per pair is fine, but just to be sure😎

Your ohm meter is your friend!

If there are 2 different pin that connects to the same internal component I'll connect only one

... the control grids (pin 2 and 9) ...

Looks like Pins 2 & 9 are "G2" (the screen grid).

The control grid is the one pin all by itself at Pin 7.
