Dear JBL Forum,
Seeking some input on binding posts upgrades to a couple of JBL speakers. I had firs researched the JBL Forum and found one post, with no replies, I hope to be more successful.

I have a few pairs of JBL 4311b’s. 4312a’s and a pair of 4313b’s. I am looking to upgrade the binding posts to a modern ‘banana’ plug connector on a pair of the 4311b’s and the 4313b’s. I also have a pair of 4312a’s – which have the banana style binding posts.

Is this fix or upgrade even possible by a knowledgeable JBL repair person on the 4311’s and 4313’s? What is generally involved if it can be done, and what should I be mindful of, things to ensure are done and things to avoid?
Thanks in advance for the input.
