while waiting on more parts and a new speaker to arrive[the old one works ok,but has some issues with voice coil alignment as well as a few small holes and previous patches that the cone's extreme fragility makes me reluctant to even attempt to fix]
in the meantime I've started on the cosmetic side..the "bronze" trim is indeed brass,and as was suggested earlier,it's not actually bronze plated but has some kind of tinted lacquer applied...some brasso and a little elbow grease quite nicely took the badly deteriorated finish off the large trim piece below the dial,that cross piece is now gleaming clean brass...i guess the question now is,being that i rather like the bronze look,what can i find to duplicate it?tinted lacquer is not something i see at wally world or home depot...
