Here’s something to try.. Use your existing test setup to measure each of the parts you have, one at at time, and select the two with the lowest voltage drops from E to C (or the highest drops across the bulb). Then take those two and wire them in Darlington, and plug them into the circuit as if they were a proper D1071
Or just be lazy and grab two at random – whatever.. 😉
If you get two with a beta of 22-24, that would give you an hfe of 500 or better in Darlington. That meets the min. of the D1071 spec.. and unless they are just total crap that can’t take a couple hundred volts, I bet your module starts working..
