Progress update. I've got my speaker done and it works great! Steve, I used your idea and removed some windings on voice coil to get it down to 4 ohms, thanks!
Problem is that now that I have correct speaker installed, I'm now back to having that loud hum I started out with using a P.M. speaker! It appears to be coming from the vibrator as it occurs even when I remove the rectifier tube. If I pull out the vibrator there is no hum. It also does it whether I use the new solid state vibrator or the old one that was in the set, but there is a slight change in tone on the old unit. Anyone know what could be causing this? I'm stumped !
