Hi All... I'm in the process of restoring an old Eddystone 730-1a receiver (all valves for you younger folk) and the service manual gives the test point voltages based on a 20k/Volt meter. I realise that some, if not all of these voltages are relative to a high impedance source and the 20k/V meter would drag the voltage down to the correct value (according to the service manual). As my old AVO 8 has long since gone, are there any suggestions as to how I can read meaningful values with my Amecal digital meter? My gut reaction is to insert a suitable resistor in parallel with the meter probes to load up the test points in order to get a valid reading. Obviously the resistor value would have to be calculated based on the voltage range that I'm trying to measure. Best wishes Malcolm M6MYB PS Wish I'd kept that old AVO................. PPS Thanks for a brilliant forum.
