This circuit amplifies signals from 0.5 Hz to 300 kHz. We found it in an old documentation. Equivalent transistors may be used. The gain is 20 dB.
The current can be kept constant in the load circuit using the integrated regulator LM350. The...
Found in older documentation this setting applies to modern components, noting that the power...
This circuit is suggested by American documentation from 1970. It makes use of transistors of the time...
