It is a classic design of the last 35 Watt amplifier, and 2 push-pull EL34, Siemens and Halske. The amplifier has been from 1954 to 1989, when it came out, except that the operation, the average activity for 15 hours a day. It is not present in damages in excess, in particular the replacement of [...]
Here’s AC power supply circuit with low voltage output (step down transformer converter). Warning! This project involves the use of dangerous voltages. You must make sure all high-voltage (120 volt household power) conductors are safely insulated from accidental contact. No bare wires should be seen anywhere on the “primary” side of the transformer circuit. Be [...]
This 12V inverter is very easy to build, cheap components that many electronics hobbyists may even already have. Though it is possible to build a more powerful circuit, the complexity caused by the very heavy currents to be handled on the low-voltage side leads to circuits. The circuit diagram of 12v inverter is easy to [...]
