Hi dont know if this is the correct section so sorry if it is not .i purchased a vhf diy amp kit from a market place twice 1st time i thought i blew the final output so obtained another one put it all together and was working and again same thing no out put .
i also this time round brought two spare outputs incase it was to do with them so i replaced outputs and still no out put could this be a cap problem in the lpf or something?
