Hi!
I'm having strange problem with rangemaster build.
As far as I have over 100+ OC44 I've decided to build this as close to original unit as possible.
I've read Geofex "help book" and here I am.

All sources telling me I should have collector voltage close to 7V but i have everything reversed.

OC44: hfe 80, 0,04 leak

Power supply - 9,3V, center positive
C- 0,8V
B- 8,1V
E- 8,2V

It's working but not sure what I've done wrong. I've used this "layout" for a build. Looks fine for me but something is not right. Can You guys help me find an issue?

Have you measured the read voltages to minus?
