SJR Looper Tests – DC vs SJR LED Driver

by · Published · Updated

This test would work better with a germanium transistor. I have some more on the way. I burned out all the others I had doing unorthodox circuit connections in testing. Instead of the a germanium I am using a 2n2222a with resistance between the base and the collector. The 2n2222a does not work nearly as well, but still outperforms DC as an LED driver.
