Hello again all, got myself a new project for the long winter coming ahead. I have acquired a grunow model 733 with a 7M chassis. Chassis only, no cabinet or speaker. I was just wondering if there is any way to be able to adapt a speaker to work for this particular chassis? The is a five pin speaker socket in this, and I see from the wiring diagram whre the 5 pins lead to a speaker assy that consists of a field coil, buck coil, and voice coil. I was hoping that the speaker assy from my grunow 1191, 11G chassis would temporarily fit to see if this thing actually works, but the wiring is only 4 pins and totally different. Anyone able to give me some tips to be able to use a new replacement speaker (i think i've seen it mentioned in other posts abount using wirewound resistors) ?
Any help would be much appreciated! Don.

I have a Grunow model 637 with a 7M chassis and it has a Magnavox speaker model I2CICI with 5 leads, marked 1000 ohms about 12" diameter.
