  1. @Jhakobe Your values are small enough that the capacitor body is short enough where the lead will protrude once you bend it over the body of the capacitor. For larger axial electrolytics, you can do what’s shown. I have no idea if these will show up in the right order.
  2. Yeah, impossible to find, at least for some of us. Maybe @henry4841can help. I just slightly extend one of the leads using the j-hook method. I’ll post a picture here later this afternoon if you don’t know what I mean by that.
  3. Just a guess. Cornwall Birch Raw, 26th week, 1981, numbers 677 and 668. Take network to Type B2 (if it isn’t already). Run a hand over the capacitors and make sure they aren’t seeping oil. Even so, most update the capacitors. If you want to do it yourself, kits are available through JEM Performance Audio. If you don’t want to do the work, I’m Klipsch authorized to do it.

  4. JEM Performance Audio 412-401-6915 Hard to beat getting the exact correct values with a single phone call.
  5. @geoff. Just curious if you used a T4A and other Klipsch parts, or after market? AL-3. Steeper slopes. Turn it up.
  6. I avoid it because it’s only 20 gauge wire, and once you crush it, there isn’t much lead material left at the end of crimp to maintain mechanical integrity, especially inside of a loudspeaker cabinet which is about the worst place possible for a network.
  7. I never could decide if it made sense on a film capacitor, especially a film and foil. ALK and John Warren both told me it only made sense on electrolytics. Wow, I just realized something - I think that may have been the only thing they ever agreed on. Does live music sound a little grainy, or is it smooth like butter. Just something to think about.
  8. Nope, but I've played with DC biasing (charge coupled network).
  9. I'm still tempted to use a fuse like the AK-3, but will need approval. Just haven't had time to deal with it. The day job has me pretty tied up right now. I've always believed that if a person is determined to blow up their loudspeakers, they will find a way.
  10. AA rolls off the tweeter at 21dB/octave. Along with the additional protection, you get better imaging and more power before the K-77 turns into a Kazoo. The AA also has significant EQ to address a peak in the K-77's response. There is a recent thread, now buried, where testing showed low level distortion exhibited by the diodes. While discussing this with Roy, he told me to either not use them or use the 100 ohm resistor in parallel with the polyswitch.
  11. @EdgarIt was a joke Edgar. There are three kinds of people in the world; those that do math and those that don't.
  12. Roy gave UT permission to let me put T2A’s and T4A’s back into production. What are you trying to do?
  13. We all need to find something else to talk about. How about that Baker Mayfield.
  14. No one ever said improvements can't be made. You presuppose that all mods are improvements.
  15. In this case, a voltage transfer function, so yes. "The transfer function of a filter is the voltage amplitude at the output as a function of the frequency of a constant amplitude sine wave applied to the input."
  16. That was kind of the point of the discussion. It was in the earlier posts - comparing numbers from the data sheets and measurements for the different dielectrics. Sonicap and Dayton are polypropylene. Tecate are Mylar. Klipsch has been using Mylar since the early 70's. We are trying to show the OP, and anyone following along, how the different dielectric material impacts ESR, DF, etc. These measurements directly influence the voltage curves and transfer function. This much I learned directly from Roy, which is why he asked me to use Tecate, and to have Universal Transformer bring back the T2A, T4A autoformers and various coils. I even had to request a certain steel type for the laminations, as these also effect the voltages. Yes, it's audible, as Jim from JEM discovered, along with many others, who mostly just quietly fix things because they don't want to be caught in the middle of this quagmire. Klipsch doesn't make their engineering processes public, so we are often left to speculate. It's not a slam on Klipsch, just the reality of it. No one was being critical, so I don't understand the heavy hand. Well, I'm out. I no longer have the emotional bandwidth for this.
