That's so disappointing to hear. That 41-300 looks so similar to the 42-400 I restored a few years back... Looks to be about the same speaker in it (though I may be wrong), but mine was a total basket case, as was the speaker (had major holes in it... I fixed the speaker (and everything else), and the sound was absolutely impressive! Did you replace ALL crumbling wires? That baby should be belting it out! There were some caps and rotten wires under the push button sector that are tough to get to. I hope you isolate the problem, and good luck!!!
