Regulators in Use & Misuse by Harry Lythall - SM0VPO. Voltage REG's like LM78XX series.

[sm0vpo.altervista.org] I seem to remember that I've posted INFO on Voltage Regulators before, but this is a nice write-up on them. I use them on gear from the 60's, 70's, and 80's, with great results. (Thank you Boomer for FWR this to me!)
