Class F amplification is a well-established technique that uses harmonic tuning to improve the amplifier’s performance. In a Class F amplifier, odd harmonics are added to the collector voltage to shape it into a square wave. The collector current, which is ideally a half-sine wave, contains the fundamental and even harmonics. An inverse Class F amplifier, also known as a Class F-1 amplifier, swaps the shape of these waveforms.

Hello everyone, I am restoring a defective MACAP/ELEKTRA bean grinder, probably type MXP. I could not find anything on the net about wiring diagrams and/or PCBs. Also no replacement parts, at least not for the generation of grinder that I have. I have the idea that there cannot be much that is defective. After all, it is a relatively simple circuit, at least that is what I thought…. On the circuit board I saw that capacitor C2 is probably missing.

I work on a poultry farm and one of the daily tasks is to gather all the dead dispose of them. We grow 45lb heavy toms and I've been putting them in a wheel barrow which is pretty hard to push once you reach about 5 birds. We have a gorilla cart which has 4 pneumatic tires and is steerable. I would like to outfit this cart with an electric motor but need some advice on what motor to use as well as how to control speed. Any input would be great. Thanks
