Atwater Kent model 20 Big Box
#4

Thanks Chas, per your dial and tuning gang alignment instructions all three of mine are way out of line. But not difficult to correct. Have been looking at the ARBE-3 battery eliminator. Since I am fairly new at old radio repair I don't have a supply of bits and pieces to build one and would have to buy every thing new or travel a lot of thrift store miles looking for a panel or box to build one on. The new schematic with info is very handy and you have given me a good amount of reading to do on old speaker horns. I don't see any polarity markings on the speaker coil assembly or leads so I'll have to see what I think after I read the material you were kind enough to supply. The assembly that holds the diaphragm and provides a means to adjust the audio coil assembly towards or away from the diaphragm was in broken and missing form. Super glue to hold the pieces together then JB weld seems to have done the trick. The diaphragm had only 1 gasket, but it seemed one on each side would be better, so I made two and will see how it works. It will sound laughable but I made the adjustment assembly out of the cut off threaded  end of a wide mouth canning jar and it's mating metal ring. More JB weld and some minor successful testing using said 9 volt battery. I can adjust the audio coils onto the diaphragm so static from tapping the battery post is very weak, adjust the coil away from diaphragm for stronger sound, then away from diaphragm till static is weak again. The test may be meaningless, but keeps me hopeful. From the price I'm seeing there's not much hope of picking another one up cheaply for parts. Thanks again.
