    will one of these work on 10 meters.

    this jb2000 doesn't have a place for a driver tube,i'm guessing its a high drive.it does have a band switch.10 to 80 meters.someone did some bad soldering in it,need to replace some wire to make it look better.already put a good power cord on it.fix it or buy a sb-220,think ill work on it some...

    hw100 mike wiring

    heathkit hw100 looks different where mike plugs in.looks like a two wire of some kind.what did the mike plugin look like and how many wires does it use.also need wiring digram.

    750 maco

    the 750 maco has 1 (8950) driving 2 (6KN6) driving 6 (8950) one of the 6KN6 tubes is bad,should i replace with same or put 8950s back in there place.it would have to have the voltage changed back to the 8950 voltage.would it be worth the change.

    maco 200 capacitor replace

    no resisters on capacitors,this maco has low and hi.it has a wire between the capacitors,the other wire uses both capacitors.both wires go to low/hi switch.
