I typed the following on a forum post and figured I may as well throw it up here. It is just some of my thoughts on using original circuit boards vs. buying new:
Some people want things original. There’s nothing wrong with running the old boards. One person may not like it, one may prefer it. I’ve certainly seen a fair amount of problems with brand new stuff. And often a new board doesn’t solve the problem because the actual issue is something else. I’ve seen new boards damaged because the original problem was not correctly repaired. In the end a new board didn’t save the owner any time or money.
