This circuit is from Motorola's 1990 Linear Databook. The transistors allow equivalents and the output power depends on the supply voltage. The power supply must be 30 V symmetrical.
Nixie-type displays are no longer used except for assemblies of people who like old technology. The...
This amplifier was found in Burr-Brown documentation from the 90's. The gain can be programmed by resistor...
The integrated circuit used in this 90's application is no longer easy to obtain today. The...
