The first Project is a 600w 50mhz Solid State Amplifier,
there are 17 pages in total and I have done them in black and white so download time is kept to a minimum. This design is a direct copy of G3WZT John Matthews, and is reproduced here as shown in the "Rad Com" which is the magazine of the Radio Society of Great Britain so all credits must go to G3WZT, and to the R.S.G.B.

TIP, If you use a 4CX350 "F" VALVE IN YOUR LINEAR,
BUT CANT GET A SPARE ONE, Then remove the two wires from the HEATER pins on the bottom of the valve socket and make sure the ends are insulated for safety, next solder two new wires to the HEATER pins and lead them outside of the case to a 6v Transformer (ac) The current drain is minimal so something like 3 / 4Amp will be plenty, and have some to spare, By doing this, you will now be able to use the 4CX350- "A" OR "B" Valve, exactly the same output, but a lot more easy to find. (Note: "F" uses approx. 27 Volts, "A" "B" uses 6Volts)
