Having just completed an 89B I'd say the bare minumum problem points you should address before applying power would be these:

1. Check the coils for continuity (and bake/seal them)
2. Replace / restuff the electolytics
3. Replace the caps in the mains block (beside where the power cord enters the chassis). From memory its 2 x 0.015uF caps - I used a three-legged safety cap with X and Y caps in it because I added an mains earth to the chassis, but those two caps need to be safety caps, not just standard ones.
4. Replace the 0.01uF coupling cap between the 75 and the 42

Then replace all the other caps, and probably half the resistors because they will all be bad

My thread here or ARF has the coil details for pinouts etc... and there is rewinding info around here somewhere. I replaced the 36 with a 77 for reliability but if you want to keep it original and it has a 36 they can be made to work.

Post pics - you can never have enough pics of restorations
