hi all im new to the forum so hi to all
i have a question that i cant find an answer to.
i have a 555 frequency generator, putting out a frequency of about 43khz.
im looking for an amplifier capable of amplifying this signal.
looking for a total output power of 50watts or therabouts. the only idea i had was to get a schematic for a 50watt audio amplifier (20khz max) and modify it to accept 43khz
the input/output impedance needs to be 50ohm as it will have a bandpass filter after it, this will then goto an antenna
i would like to use the 43khz frequency on the amplifier rather than a 10.75khz harmonic
any help on how to modify an audio amp would be great, a schematic would be even better.
cheers guys
