  1. You've got a dead short through the fuse to ground. In my experience with my old Yamaha, it would not close the speaker relays with a failed resistor in the power supply. That failed resistor took all of the output transistors in one channel when it went. You may have similar problems. You need a service manual and/or professional help. John
  2. Stevie Ray Vaughn! Tinsley Ellis Robin Trower The Edge John Hiatt Jeff Beck Santana Jeff Baxter See a pattern? John
  3. HornEd, http://ww2.onecall.com/PID_12928.htm John
  4. Very high frequency oscillation? Say 15kHz? John
  5. Four feet will work just fine. Mr. Paul's design for false corners are 4 feet horizontally from the corner to the outer edge. He uses a pair of those false corners in his house, now. John
  6. http://www.amazon.com/exec/obidos/clipserve/B000002LT2001004/002-8568572-4373635http://mfile.akamai.com/3196/rm/muze.download.akamai.com/2890/us/us_rm/1200/124561_1_04.ram?obj=v10212 That picture gave me a vague feeling of a song by Loreena McKennitt. It turns out I thought of the name just before I read John's last reply; "The Lady of Shalott"! I guess the painter did his job. John
  7. Either Dynamat of rope caulk will work. Rope caulk will be cheaper and easier. I've done both. John
  8. Try Cornwalls first and Forte/Chorus second. Heresies will have to have a subwoofer to be satisfactory. I use 2 big subs with my La Scalas, even. John
  9. Tony, I'm glad to hear you've got news. PLEASE post and send out an e-mail if you get a firm date and time. You have a recent e-mail with the fan klub's attendees and a couple of others that tried and couldn't make it. John
  10. http://www.mrspaulwklipsch.com/ Plans are being made as we speak concerning a book signing day in Arkansas, and the latest is to schedule it to be at the Aerospace Museum in Little Rock with the governor Mike Huckabee in attendance. It should prove to be an exciting time for all! The date of this book signing has not been finalized but if all goes well with the printing of the book we are probably looking at somewhere around the 18th or 19th of March. ROADTRIP!!!!! John
  11. When is Mr. Paul's birthday? I can't find it in my notes. Won't he be 96 this year? John
  12. Listen to them for 6 months before you make changes. Change only to solve problems you hear. John
  13. My front La Scalas were done professionally with a Minwax stain and satin polyurethane. I'll bet he used a "sealer" to keep the stain from looking blotchy. Home Depot has it in Minwax and other brands. check out the pics on my site. John
  14. You will need another power amp. If you search this site, you should find a schematic of the circuit Mr. Paul recommends for generating the center channel signal. John
  15. Just flush your electrons! It only Hertz a little! John
  16. It takes time to flush out all of those bad electrons. John
  17. Be sure to test the bass drivers for an open voice coil. It one coil is open, you'll get diminished bass, but that driver will appear to move because it is in the same chamber with the working one. I seriously doubt the crossover is bad. John
  18. P=IxV and V=IxR Where P= power, I=current, R=resistance and V=voltage. Rearranging the above, P=V**2/R (V squared). Power amplifiers are essentially voltage sources, meaning their output voltage is pretty much the same no matter what the load is. If V is held constant and R is changed power is changed. If the resistance is doubled, the power is cut in half. If the resistance is cut in half the power doubles. Since we don't live in a theoretical world, there are limits, particularly in the power supplies of amplifiers. As the resistance falls, the power supply is called on to put out greater amounts of current until it just can't anymore. Below that point, the power doesn't increase linearly and the amp's output voltage actually falls further limiting power. It appears your amp is current limited just above 4 ohms (it can't double its power from 8 to 4 ohms). Going the other way from 8 to 16 ohms, it won't be limited and the power will halve, i.e. 90 watts. If your amp is underrated and can actually put out more than 180 watts at 8 ohms, it will put out more than 90 watts at 16 ohms. John
  19. Those are Klipsch components in a home-made box. The squawker is the Heresy 1.5/ Heresy II squawker and the woofer looks right. That's some sort of Klipsch network. Only the tweeter is missing. It must sound rough. John
  20. There is no ideal or "good" ceiling height. It is acceptable that the ceiling height is not an integer multiple of another room dimension (or close to it). many of the music halls of old that were said to sound good had what we'd now call a catherdal ceiling (a high, inverted V). I've had two houses with that ceiling in a rectangular living room that sounded pretty darn good. If not that, I'd next choose a sloping ceiling, falling to the front of the room.

  21. That looks like superb in-room response to me! I'd look at some rugs or wall tapestry to help with the 8k bump, it it is still there after you correct for the instrument error. John
  22. Hi, Bill! How ya dooin'? Are you all busier since September? Is that a dumb question? John
  23. In all fairness, the cat-5 cable to the KLF-C7 did make a small difference. I still have trouble describing that difference, sort of smoother and more detailed. I had the wife and both kids helping. The boys didn't mind, Cathy thought I was "touched". i had trouble typing for a couple of days afterward. John
  24. Standing waves are caused by the dimensions of your room. They are a resonance that occurs at some frequency (or frequencies) and every multiple of that frequency until the multiple gets high enough the room absorbs the frequency. An example might be 40, 80, 120, 160, 200, ..... Essentially, your room is resonating like an organ pipe. Other than changing the size of the room, thatr's nothing you can do about standing waves. The effect of standing waves is that at some frequencies and at certian places in the room, the bass will be strong (peak). A few feet away, or at a different frequency you'll have no bass to speak of (null). I can assure you, your room has standing waves. Hopefully, they are not too prominent. You can adjust the position of your speakers so that your listening spot is not located in a null or a peak. Another trick is to use 2 or more subs in different locations. Since they are in different locations, each one will excite standing waves in different places. With any luck at all the peaks from one will hit near the nulls from the other and you'll have fairly even bass response throughout the room. John
  25. "Just because I'm paranoid, ...." Thanks, John, I needed that! John
