Hi
I have performed various tests with just a resistor as a load and photographed the results.
Please note the scope setting as these may have been changed for different photos.

Photo --- scope probes--- Function sw--- load
Photo1 the resistors I used both about 6k ohms each
Photo2 --- anode-cathode, switch on test, 6k load,
Photo3 --- anode-cathode, switch on test, 3k load,
Photo4 --- anode-cathode, switch on leak1 or 2, 6k load,
Photo5 --- anode-cathode, switch on htr, 6k load,

continued in next post.
