model 71H shadow meter
#1

My recently acquired 71H code 225 has the metal housing and lamp, and the escutcheon for a shadow meter, but the guts of the meter are not present. The wires needed to connect from the terminal strip to the meter are not and appear to have never been in installed. The wire connecting the A&B tabs of the terminal board is still in place. It would appear this unit was partially setup at the factory for the meter with the exception of the meter. I cant find a part number or what I should ask for the forum ti install this. Should I be asking for any year/model of the shadow meter or should I ask only for a 32/33 71 shadow meter? I included a link to a shared album on google. I think you can copy and paste it in a browser. The last picture shows the meter housing.

Yes - the shadowmeter housing is present, but its guts have been removed. Most likely, it failed at some point and instead of replacing it, someone removed the shadowmeter "guts" and rewired things inside the radio so that the shadowmeter would be bypassed, allowing the radio to function without it. It would not have left the factory like that.

Any Philco shadowmeter made from 1932 to 1935 should work. Some 1936 shadowmeters have different resistances and may, or may not, work properly. And 1937-38 shadowmeters are constructed completely different, with a different mounting technique, so these will not work for you.

Ron,
Got it. Thank you for taking the time to respond. I'll post a WTB with this info.
