  • It's a good idea to check the response of any choke you're going to put across an amplifier output.

    Great video Steve, how do you remove that unwanted response from the choke?

      add more wire, you need a +_ 2.5 mH (milli henry) choke at least, that covers any hf vhf frequencies. It's not the Alpha and omega.... but it sure handles anything you throw at it hf amp wise.

    Parlay. We have ourselves an accord.

    I think the wire is too thick, it needs to go up in smoke as a warning that the dc blocking C is defect. :-)

      nope, it needs to trip the amp ht circuit breaker by going over current, if it goes up in smoke and burns and open circuit there will still be ht on the circuit, that is after the DC blocking cap failed as well as the protection choke normally 2.5 mH. I would agree that there needs to be added quite a number of turns... and the choke need to be able to trip whatever you are working on amperage wise, lets say 220v 7 amp, then it must be able to handle that current without failing tripping the amp, it should also not be resonant at any of your working frequencies as well as the odd parasitic frequencies ... clever little buggers these chokes :)
