Hi People,
    does anyone know if there is a subsitute blower available or how to quiet down this blower?
    There is a problem on 15 meters(only) with not getting full output. There is a big 10 ohm wirewound ceramic resistor in series with the HV (connected in series with the plate RF choke), its mounted in front of the blower input, the ceramic has flaked off one side....any connection betwixt these ?
         thanks, 73, John
