This circuit was obtained in an old European publication on FETs. The FET admits equivalent and the feed must have good filtration. Signal input cables and output cables must be shielded.
The integrated circuit used in this project is unusual. We found this configuration in Motorola's Linear...
This circuit with only one transistor was found in Japanese documentation from the 1960s. The...
The operating frequency of this circuit is 465 Hz and the input voltage is 12 VAC. The circuit is...
