And stay away from switching power supplies, if you can. They've come a long way in the last 30 years, but give me a solid linear transformered supply anytime, over a switching.
“I am often asked how radio works. Well, you see, wire telegraphy
is like a very long cat. You yank his tail in New York and he
meows in Los Angeles. Do you understand this? Now, radio is
exactly the same, except that there is no cat.”
-Attributed to Albert Einstein, but I ripped it from the latest Splatter .PDF March 2025 issue.
