This is my Inspire Hotrod. I have tried new production Genalex KT66 tubes, Tung-sol KT150 tube, vintage NOS Western Electric 350b tubes, and new production Tung-sol 7581a tubes. My favorite is the new production Tung-sol 7581a tubes. I have also tried various 6SN7 tubes - NOS RCA, Shuguang treasures CV-181z, and new production Tung-sol - I keep coming back to the Tung-sol tubes.

I am using a McIntosh C2500. I swapped out the McIntosh/JJ tubes and I am now running Genelex Gold Lion new production tubes, it was an improvement over the OEM tubes.

What I found interesting while working on my 1996 LaScalas was that the Klipsch factory wiring used 18gauge for the woofers and 16gauge for the squawkers & tweeters from the crossovers.

I just got done replacing all the woofer wiring and the screws going from inside the Bass Bin to the Bass Bin connector block. Klipsch used 18 gauge wiring and I replaced it with 14 gauge wiring. Klipsch used steel screws and they have corrosion right where they would have been in the connector block, my new screws are stainless steel. The woofers now measure 3.3-3.4 ohms on both speakers at the crossovers. Then it was time for a listening test, more bass and better sounding bass.

I just got done closing the bass bins. The woofers both measure 3.3-3.4ohms with my DMM at the woofers. So the woofers are good. Then I started checking the wiring it measures 0.0-0.1ohms and the Bass Bin connector block in the tweeter/squawker area measured 0.0ohms. The screws that goes from the inside the Bass Bin and screws into the Bass Bin connector block seems to have approximately 0.9ohms measurement. Looks like it is time to correct the woofer wiring, replace the screws, and Bass Bin connector block. I originally measured the woofer using the wires that I removed from the crossover. I now have the left woofer down to 4.3ohm when I measure using the wires that I removed from the crossover. Thanks Bob W.

My woofers in my 1996 LaScalas measure with a Fluke DMM Left 5.9ohms & Right 4.4ohms. New woofers from Klipsch are $129.23 each and Bob Crites woofers are $240 for a pair(per Bob Crites website). I am planning on replacing my woofers and I am looking for opinions. I am the 3rd owner of these LaScalas and in 2011 one of the K-77M Tweeters had the diaphragm replaced(magnet dated 18th week of 1996, but a sticker on the tweeter say 12-21-2011 and solder on the terminal rivets does not look professional). I am thinking that whatever damaged the tweeter also damaged at least one woofer and since both woofers look identical possibly the woofer got repaired or the first owner bought a pair of used Klipsch K-33 woofers on eBay. The person I bought the speakers from in April 2017 bought them from the first owner in 2012. Thank You, Bob Walters

Today my pair of National Union 350B tubes arrived. Put them in my Inspire Hot Rod, also put in a NOS RCA 6SN7GTB. Thanks for letting me know about the 350B, the La Scalas sound nicer now.

My La Scalas made in Hope, Arkansas. My McIntosh MCT450, C2500, and MC225 made in Binghamton, New York. I did buy my all my equipment used.

I brought home a pair of 1996 LaScalas April 13th. You are right, mine also fulfill my musical needs. I like the sound of mine so much that I have no plans on modifying them. I am afraid to change anything on my system and lose the sound I have now. I am lucky that my room only has one corner where a KHorn would work, so KHorns are out of the question for me.

Thank you for the advice. Once I refinish the cabinets they will go on the floor, it is easier moving them with the dollies while fixing a couple small nicks, sanding and refinishing them.

No matter what flash option I used on my Nikon P510 I just could not get a picture showing the details of the lower part of the speaker. They have some minor cosmetic flaws which I will correct. I am presently using my Dennis Had Inspire HotRod SE tube amp with KT66 tubes. Next week I will hook up the McIntosh MC225. The picture shows KT150's in the Inspire HotRod, the LaScalas sound better with the KT66's.

Last Thursday evening I brought home a pair of black LaScalas. They sound great and are all original. The serial numbers are 198592416 & 198592417 and they decode to July 17, 1995. But the speakers have a final assembly sticker of 10-22-1996 and the date codes on both tweeters are 9618.
