I'm about to begin to restore 2 620 chassis. I'm not sure yet whether they are the early or late production run. My question is if they are the early run, should I update them with the later changes?
I don't know that I would, Derek, unless you've been restoring sets for a while and feel pretty confident in your work.
Please don't misunderstand - I'm not trying to be critical. But if you recap the 620 with the original circuit and it works well, there is no need for a change.
One man's opinion...your mileage may vary.
