My RF Amplifier project is making progress!
The RF amplifier will work with the tetrode tube GU-84b. On the left you see the anode voltage transformer - that beast delivers 2 500 Volts at 2 Amperes in continuous service. Current work is to program the controller that handles the operation of the power supply. The controller is based on the AVR microcontroller ATmega16 - a very flexible 8 bit CPU that can be programmed in C language using the GNU C compiler gcc in its avr-gcc incarnation ... All this is done on a MacBookPro using publicly available tools on Mac OS X (10.5.2 currently). It's pure fun - I can tell you. You should try it one day... Oh, btw, the transformer weighs a woppy 52 kg. Building the cabinet for the power supply is just about to be completed - and was not an easy task. But hey, it's just a hobby ... Now for the details - An AVR code excerpt: // ---------------------------------------------------- // MAIN // --------------------------...
