I recently bought a uTracer6 and I am assembling it. After completing step 9 - grid bias circuit construction I moved to the grid bias circuit testing.
When I applied -50V to the grid bias voltage, I selected "heater on!" and "measure curve" in the GUI. When I measure voltage across grid and cathode on the 4 terminal screw block, I only get approximately -2.8v instead of -80.
I checked my soldering with a scope and didn't see any issues with it.
Does anyone have any suggestions on what the issue might be?
(p.s. the schematic seems to be configured wrong vs. the pcb for parts p40, R41, R43, and R45.)
Thanks,
Tom
