Default Steve Bench PP loadlines

Hello (saviours),

I'm trying to get the hang of PP loadlines, first following s. Bench' manual with pencil and drawer but I only get a huge headache and cra**y looking lines (my head now has an infinite internal resistance and zero gain)

I've downloaded the spreadsheet zip but there are still a few variables I'm unable to fill in:

1) Horizontal volts / =

2) Grid volts / step

3) I suppose the Rp value is expressed in kohms in the spreadsheet?

Hopefully someone can help me fill in these blanks and open up a whole new world of unkinky pp pleasure!!!!! FWIW I'm trying to simulate a 12b4a pp

Here's a link to steve's tutorial(, the spreadsheet is on that webpage (

A million thanks for any replies
