This stabilized source can supply currents up to 700 mA and the output voltage is close to 15 V. a little less with the load. The power transistor must have a good heat radiator.
This circuit was found in a 1977 RCA documentation. The source must be symmetrical, but the...
This Hartley oscillator can be used in tests or as a signal injector. The transformer is the type...
We found this circuit in the November 1985 issue of Radio Electronics magazine. It uses TTL...
