I picked up an RCA V-100 at my local flea market this past weekend. This model is an AM Radio / Phonograph combination. The cabinet, dial, phono, knobs, trim etc are all in pretty decent shape. The chasis looks pretty original (from the top anyway -- haven't removed it yet). All tubes tested good.
One item I did notice that I will need to tend to along with the caps --- the speaker cone is about 90% disintegrated. This particular unit has a 5" electrodynamic speaker -- and from what I've gleaned - I'm not likely to find a replacement for it too easily. I haven't tested the field coil yet -- but presuming its good -- and since I'm a purist at heart -- I'd like to try to salvage the field coil and retrofit a new pm type speaker in the basket of the original one. I'm interested in hearing from anyone that's tried this -- to learn the caveats! Additionally - just in case the coil is bad - how would I wire a replacement coil/resistor combination to compensate for the original field coil??
Thanks in advance
