    Can’t accept the credit. Earl pointed you to Rob’s thread... But I must say, I am impressed.

    Well done!

    Nice job, Paul! Eventually, we all come to this: finding ways to save what we have because we cannot get it any more.

    Nice rug, by the way. I like its patterns.
    Out.

    This plant is my uncle's, we have a lot of JBL in my family, I have a slightly different plant..... after having tried so many JBL I always remain tied to 4333, with a slight update of the filters and an adequate environmental treatment I prefer them all.... but it's just my taste.... moreover, the 4333 are satisfied with a good high current class A amplifier while for others you have to have a heavy hand often losing in refinement....

    There is a possibility that this may sound better in your ears.
    There are many who think they can replace capacitors and hear improvements.

    But, if one tries to be realistic and think the following, the top models of JBL have never been produced in very large numbers. If it is the case that a few capacitors of possibly better quality will give significantly better sound what would it cost JBL?
    JBL, which is a very large customer, does not pay the same prices for components as one that buys 10 or 100 pieces.
    What would a small extra cost for capacitors mean for the price of the product to the consumer?

    Probably nothing.

    I am very happy for you and impressed that you have been able to repair these speakers and make them work once again. That said, while I tend to agree with Odd, if you are enjoying them even more after the cap swap, good for you…. Keep it up!

    A counter example: JBL made 100 pairs of its top of the line 4345, but according to G.T. the sound quality was compromised by the cost engineer's choice of a cheesy biamp switch.

    Yep, and I think there are likely many other examples where the bean counters made choices we would disagree with.

    In this particular case however, when these speakers were designed and built the K2-S9800 was JBL's flagship speaker and GT was actually being listened to at that time. I doubt that a significant improvement would have been left on the table by such a simple and inexpensive change.
