Tales From the Chip: LM386 Audio Amplifier
I have a question about capacitors in general (I'm trying to restore a Hallicrafters S-38A receiver, and this topic has me stumped). In your instructions, you say use a pair of 100 uf electrolytic caps, and 1x 1000 uf ceramic cap. I always was under the assumption that electrolytic caps are used for higher values of capacitance, as long as the polarity is observed. Why 100 uf electrolytics and a 1000 uf ceramic? Maybe I missed something?Excellent presentation, by the way. Thanks.

To prevent grass build-up on the underside of the deck, after you get ALL the grass off, wirebrush it (don't forget to take off the plug wire), get it squeaky clean, then spray paint it with some graphite spray, like E-Z Glide (Tractor Supply has it). Just remember to spray in a well-ventilated area, perhaps even with a respirator mask. Also consider safety glasses.
