Backwards Vacuum Tube Curves Photo

 

Jim,

What did you do to create that screen shot you labeled "Backwards" of the
vacuum tube curves that you uploaded to the 576 Curve Tracer album. I have
tried several ways in my head to figure out how you did it with no success.

Actually, I found that photo on a forum.
?
I'll try to find it again and contact the guy.
?
I couldn't figure it out either, unless he rewired the CRT!
 

I believe it's mine -- not with tubes, some medium power bipolar transistors -- the "ascender" slope is negative -- this just started to happen recently. Happens with both N and P type devices. I haven't diagnosed the problem yet and am open to recommendations.
