Has anyone here replaced a model 70 speaker with a modern p.m.? If so, what method of bypassing the field coil did you use (I have read that a choke is better than resistors) also, what would be a good output trans to look for? I have an original model 20 speaker but the transformer is different.
Any information would be appreciated. Todd
