> I found a model 90 10.5 speaker for my unit on ebay. But sadly the transformer on it is for the push pull unit. So I am lucky my original transformer is ok. So I will swap that over.
As you know, the 90 I restored is the cathedral version, so it uses an 8 inch speaker. The job of switching audio output transformers is basically the same, however.
