Would your suggestion then be that these others also be replaced?

Roy -

You could replace the ones which are over. I would always test them out of circuit first, but then, I am a professional, using professional equipment including a vacuum desoldering station, so it is likely easier for me to isolate and test components than it is for you.

When it somes to the ones which measure under, if it is easier for you, go ahead and replace them - replacements are neither rare nor expensive. You might want to test the old parts after they are pulled out to see what their out-of-circuit values are, compared to their in-circuit values.

I gather from your first post that you are new to soldering. Here are three important rules:

1) Too little heat or too much heat when soldering may lead to problems.

2) Always remove old solder before re-soldering. Many of us use desoldering braid or a pump-type solder removal tool like an Edsen Soldapullt. I suspect that fairly few of us have a vacuum desoldering station or a hand-held vacuum desoldering tool like a Hakko.

3) A good solder joint begins as a good mechanical joint. Use longnose or needlenose pliers to tightly wrap leads or wires around terminals of lugs before soldering them.

I have a fourth rule which I think works best. I only use lead-tin solder (mine have flux cores). Lead-free solder does not seem to work as well for me as does the lead-tin solder that the factory used.
