Results. It worked! Your suggestion about the pinout was correct. Using the 6-volt wall-wart, I tried the combination three different ways: with both the 10-ohm resistor to the Base and the additional 10k resistor in the R2 position, brightness went from zero to about 70%. I removed the R2 resistor and got a longer stretch of zero, then a ramp-up to about 60%. I removed the 10-ohm resistor to the Base as well, and got about the same results. However, I also switched the wires to the full-power position, and that worked fine. Full power.So I will solder the circuit up and leave a gap for trying different R2 values. Apparently, it wasn't my breadboarding that was the problem. Using the breadboard just made for a lot of flicker in the panel. Thank you.
It worked. A complete range, from dark to bright. Clockwise. Thanks.Give it a try
ElectricSpidey, Bernard, et al., in case any of you were interested (probably not), I haven't given up, stopped, lost interest, or moved away. After a series of unsuccessful attempts to build some old kits I've had since forever, after seeking comments about my lack of success, I stopped building circuits temporarily. I've ordered a more powerful soldering iron and invested in things like flux, lead-type rosin core solder, all stuff I didn't know enough to use previously. I also started watching YouTube videos about soldering. So I'll be back.It worked. A complete range, from dark to bright. Clockwise. Thanks.
