Dear Kevin,

From LL1660 spec sheet.

Alt. V (new!)
2.25 : 2 + 2
Single End to Push Pull Interstage!

I'm using Single Ended to Single Ended (one D3a to one GM70).

Best regards,
RPS

Sorry, but we will have to improvise to get a diagram. Use the left hand side of Alt V for the D3a and the left hand side of Alt S for the GM-70 grid with pin 4 connected to the GM-70 grid and pin 9 connected to ground.
