  1. You should measure a coil while it’s on the board, both inductance and DCR, and match it.
  2. When the weather breaks I will probably visit Cory. I’d like to hear all of the new stuff.
  3. I’m guessing here, but it might be a Torx bit #20 Yes, the networks are on the back of the terminal cups. Just check to make sure there isn’t anything obviously loose. I wouldn’t go any further than that. Aren’t these still under warranty?
  4. I think the pictured networks are the AK-5’s from the 60th Anniversary Editions. Those are probably not available. Note the rebranded Bennics and one less resistor in the low pass. This adjustment was made because they sealed the backs up. I was told this by Mark Kaufman. This picture is also an AK-5, but on one board with Mylars. These may be available. This is the network part of their normal install in the newer sealed back designs. The comment above about the tweeters being different might be true, I think they might curve a little differently. Seems I remember @Chief bonehead alluding to this.
  5. The AA’s I built you will work without having to make any changes.
  6. Never thought I'd see the day where people are wetting themselves over a dollar Mylar cap. Too funny.
  7. It’s because they’re stacked film and foil. It was a great part. Film and foil will always sound smoother and cleaner than metallized. I was of course joking with the “if I can’t hear it, they’re lying” comment - but I do think the differences in capacitors using the same dielectric and build are grossly overstated.
  8. I hate that site. If I can't hear it, they're lying.
  9. I stopped when the pandemic hit. I haven't had anything since last March. I started teleworking and they made me responsible for the junior engineers, so I had to give it up.
  10. I follow Steven (Youthman) on YouTube. He had a pretty good video of him troubleshooting the problem. Steven swapped tweeters, networks, etc. I think Randy was just saying it was process of elimination. Most of the time it will be a capacitor related issue. We are just saying don't call yourself a repair center if all you do is send out capacitor kits.
  11. Nice catch. No, I was wrong. I was thinking Type B.
  12. The tweeter on the AA is attenuated by the T2A.
  13. Uh, no. They always run a diagnostics test. That's how they get the code.
  14. What Al taught me. Now, this is using 1 kHz. I have no idea what Klipsch is using/doing.
  15. The reason given for not shipping wasn't "in my expert opinion". It was - don't want to risk having them damaged or lost in the mail. Anyways, back to the capacitor measuring thing: I've asked the question(s) numerous times, both here and on the Klipsch Owners Group page on Facebook. On Facebook, I tagged Trey with some questions, and never got a response. Last year, Trey posted a picture of him measuring a new 2.0 uF Mylar, and the tester in the background showed an ESR of 2 ohms, which I would consider terrible. However, I could not tell what frequency he was using for the test. I even posted a picture of Al's ESR on a 33uF Mylar, which came out to .026 ohms. So, the answer from me would be "I don't know" - and I have simply given up expecting a response or straight answer on the matter.
  16. That's why I built from scratch. All of the parts are measured/tested by the vendor, and I just had to assemble. If the end user had an issue, I had them send the networks to my warranty center. I thought all caps sounded the same and that we were hearing things. Good to learn that I was right all along.
  17. Yet when Youthman tried to ship his networks, he was told not to, and was just sent the capacitors. It could just have well been an autotransformer failure. I'm basically retired from doing this kind of work, so I'm just speaking as an observer.
  18. This is just funny. Yeah, a 4 inch "woofer" isn't going to get you there with the large scale stuff. I am looking at them as an alternative to a sound bar for streaming on the TV and music from my phone. These are examples of things you don't want high resolution with.
  19. Everyone is getting stressed over nothing. Your room will have more impact on the sound than the difference in these drivers. Everyone also hears differently. We are not walking microphones and we don't listen in an anechoic chamber. While not technically correct, there is nothing inherently wrong with using the M in place of the V, or using the Type AA with either. Your ears/brain are more forgiving to small changes in frequency response than they are to distortion. If you like the Klipsch house sound, and will sleep better at night knowing everything is the way Klipsch wants it, then follow their recommendations.
  20. You could build the AL-4. The schematic is available, just connect the dots. Klipsch uses inexpensive metallized polyesters, you can order them from Erse.
  21. If he was fighting cancer, he would have been immunocompromised. Even worse if he was on chemo.
  22. Didn't PWK do a Dope from Hope on this. I think the main issue was turn on/off transients from the older solid state amps. Fuses aren't fast enough for that, and neither are polyswitches.
