Magazines Radio 1994
Learning scheme in the radio magazine for the year 1994 have found an interesting regulator circuit with chip LM, became interested in the solution just because burn IC LM 317 case it is very difficult, so I sometimes got out with her, and she was very warming and parameters were outrageous, but not burned, simply, "oak chip". Needed a pulley to protect the acoustics amplifier assembled according to the scheme of radio magazine, 1985, to the last time everything worked well, but CT 805 shot column and burned. So I decided to look for something on the topic, in the Radio magazine for the year 1994 found something and as a result gathered something working. But the scheme as it is not earned the right, power gave 26.8 volts and tried the divider to adjust, as did not try, did not come out the output current is why it was not regulated even changing the resistors from 6200 and 300 Ohms. Gave up and built the circuit on a different principle, tied to the appearance of a constant component and cutoff transistor in the load which is relay RS. But if you want to look at this scheme then do not be lazy, here is all the logs for the whole of 1994, look.
