  1. Read where? That would only apply to electrolytics exposed to high voltages and/or heat. They can last a surprisingly long time in a loudspeaker network. Film types can last 50 years or more, which is how old the cans are. They may not be as good as new, but nothing to panic over unless they are leaking or you notice a problem - usually low tweeter output. Still, I encourage people to replace them instead of waiting for them to leak or fail. 
     

    20 years for film capacitor death is bs.

    They don’t sound like Klipsch speakers anymore is the top reason I have seen from those who switched one out and did an A/B.


    I understand the appeal of mods and tinkering. It is hit or miss though. A mod loved by some is disappointing to others. What I don’t understand is how someone can completely change the sound of the loudspeaker and insist “it’s still Klipsch”. 
     

    Not promoting modifications on the company message board is a small ask by Roy and Klipsch.

  3. Klipsch Support doesn’t monitor the forum, and even if they did, there is no guarantee they would know.
     

    Roy only checks in once or twice a day and it is highly unlikely he reads every post. 
     

    There are less and less of us around that even know what you’re asking about. 
     

    In what section did you post your question?
     

    Is this it?

     

    If not, there are many other audio forums.

  4. Well, everyone knows Roy and Klipsch could care less about support for vintage Heritage. They will lie, mislead and do whatever it takes to get you folks to drag them to the curb and buy new speakers. Klipsch also has an incompetent engineering department that’s afraid of being shown up by third party vendors, where the super smart people work - that’s why they don’t want us talking about them here! 
     

    All of them networks look just like Klipsch so they must still be Klipsch! Yes yes I know the parts are all different and it sounds different but prove to me it’s different! It’s a factory spec upgrade! 🤪

     

    lmao. Some of you have lost your damn minds.

  5. People ask for proof, and when you give it to them, they don’t listen. It doesn’t matter how many times or ways you explain it to them. 
     

    Measurements were provided here, for both capacitors and autotransformers. 
     

    I just posted ESR measurements on the Vintage Klipsch Fans Facebook page a few days ago. No one really cares, either due to confirmation bias, or simply an inability to grasp the implications.  
     

    I was going to post Boxler’s amazing results on the autoformer with some of my own measurements. I have decided not to waste my time. It’s an exercise in futility. 
     

    Considering what has transpired here over the last year it is astonishing that there are still people who think that nothing has been proven or discussed at length.

    If it ain't broke, don't fix it.

     

    If you weren't experiencing a problem; if you didn't test the capacitors with an ESR meter or test for an out of range capacitance value

    I see no reason to replace them.

     

    I'm with Bacek on this.


    Sometimes there is a thin layer of oil on the surface of the can. You can feel it on your hands after handling. They should be replaced at that point. No reason to wait until it’s leaking on the board. I’ve measured a lot of these over the last year and ESR is typically twice that of a new Mylar - around .80

     

    To the OP. A low ESR polypropylene will tip the balance forward. The speaker will be too bright, almost painfully so at live listening levels. 

  7. Here it is with the AK network. I know from John Allen that it was the driver used to develop the AK network in anticipation of the EV replacement (K-55-M). I confirmed this with Jim Hunter.

     

    EDIT:

     

    @geoff. Any explanation without confirmation is just conjecture, and since you are not the original owner of those LSI's, we can't really say for sure what networks those speakers shipped with. What are the serial numbers of your speakers?

     

    Another explanation is simply what Randy said.

     

    I don’t make the recipes. I’m just the cook. ¯\_(ツ)_/¯

    Well, the Klipsch FACTORY INSTALLED K-55-V dual phase driver in the La Scala Industrials using the AA crossover runs just as high as the K-55-M, and it turns out the frequency response results were based on test samples of the K-55-M that do not reflect final production units. 


    Are you the original owner of your La Scalas? Do you know their entire history? A lot of these systems were abused and overdriven. Mismatched drivers and networks are common with them. It doesn’t help that people are being told it doesn’t matter what networks are run with what drivers.

     

    I feel like you might be conflating issues on the last part of your post. I’m pretty tired, so I may not be getting what you are saying.

    I am wondering about not using the Atlas two piece phase plug K55V with the AA Type because it was available ca. in 1981 when the Type AA crossover was still in production until 1983?

     

    I don't know how to answer that. It was a transition period. Maybe the AL/AK series of filters weren't ready yet so they used what they had available to them. It's a question for @JRH Jim Hunter.
