40 watt

How This Circuit works When see a circuit as Figure 1 Many people would doubt that. This circuit will be amplified up to 40 watts. (If as the RMS will is about 17.5 watts at load 4 ohms). You do not insult it because the many circuits that were contained in IC1-HA13001 of Hitachi there. Makes a...

A 2 stage 40w amp using 28v devices. RF input power should be between 0.5 and 1 watt. The diagram below shows a 2N3375 driving a 2N5643 but there are many other devices that will work. I used these 2 transistors just because they were cheap at the time. If any of the variable capacitors are at...
