This Mullard circuit was found in a 1969 documentation. It uses complementary transistors on the output and does not need a transformer. The bandwidth goes from 100 to 20 000 Hz.
This reflex receiver for the mid-wave range employs germanium transistors of the time. We found it in...
Any power MOSFET that supports the current of the controlled stepper motor can be used on this...
This circuit was obtained in a 2001 Poptronics. The magazine no longer exists in its printed form,...
