Model 89 Restoration Suggestions
#2

Speaker from 96 cannot be used in 89 as the 89 has a single tube output amp and the 96 has two 45 tube push-pull.

Now what you could do is to use a PM speaker connected to the output transformer's secondary. Provided the rest works.

Now what I am not sure of is how you are going to test it considering the radio chassis has not been recapped etc.

So, this said, if by saying all this you are implying you want to try the chassis without making sure first it is fully reconditioned, then I'd strongly urged you not to do this.

As for "I should start from these capacitors" - you should start from ALL capacitors except mica ones. Round up everything electrolytic and paper tubular or backelite caps and start ordering.
