Philco 38-5 shadow meter
#5

Bob, your doing fine. Your coil seems to have the right resistance, good! Morzh's #2 and 3 are the next steps. Follow Chuck's suggestions. Keep in mind that the action of the meter is dependent on the strength of the signal being received, not necessarily the "volume" of the radio although certainly related. It measures the current flow to the plates of the tubes in the front end of the radio. A good antenna is needed for it to move properly. We are guessing (good guess) a sticky vane or weak magnet. With a strong local station you should get some movement. Hence try 2 and 3.
Good luck Jerry
