As in woe is me...
Just started work on restoring this model (I had previously restored a 41-265 console for a friend and liked it so much I sought out the table model version). When I took the chassis out of the cabinet, I knew something was amiss, as the speaker was just flopping around not mounted to anything. Held in place by the two wires attached to it. One of which had the end soldered to the pushbutton support bracket.
So, someone years and years ago substituted a permanent magnet speaker in place of the original electromagnetic one. The replacement speaker measures 2.8 ohms across the terminals, which is pretty darn close to the 3 ohms called for on the schematic. My question is, how can I safely make this speaker work in place of the original electromagnetic? I remember this was discussed in the past, and I seem to recall adding a resistor was in order, but if someone could point me in the right direction, that would be great. It may very well have worked, albeit not too well just flopping around in the cabinet.
Here's a link to a PDF file of the schematic. I have the code 121. And yes, I spent part of my Christmas Eve working on a radio
Merry Christmas!
