Default Screen driven EL36 / 6CM5 /PL36 /25E5

Hi folks,

since there has been some discussion on screen driven deflection tubes here recently, I measured EL36 prebiased with Eg1 = -15V, -20V and -25V (for Eg1 = 0, there is a Philips/Miniwatt sheet available somewhere on the Žnet).

In the case of EL36, while very good linearity can be obtained (if you use a CF driver for g2 being strong enough), I really think it is not worth the effort: Just take a look at the EL36 trioded strapped (extended range) curves which can be found at the same location at my web site.

EL36 screen driven and triode strapped curves

If in doubt, just measure.
