Yes, I definitely need some sort of temporary speaker set up. At the moment I get a loud ticking sound on AM and a hum on shortwave. I need to get this onto my bench for trouble shooting. If I use a PM speaker what kind of wattage do I need for the resistor to replace the 1700 ohm field coil?
Thanks,
Keith
