  1. The vault has arrived safe and sound. Itll stay in our warehouse until a forum member requires it to protect a pair of Cornwalls.


    I was unaware that it's attached to a 48" wide pallet. The height of the vault, including pallet, is 33". I was able to turn it onto its side to fit it between the racks in my work van. That's ok when empty but I wouldn't try it with Cornwalls in the vault.


    This thing would all but guarantee that your Cornwalls would arrive in the same condition they were in at departure.


    I've attached a few photos to this and subsequent posts so that you can get a better idea of what the vault is and what it could accomplish.

    Michael-

    Meeting you was priceless but listening to Take Five from my laptop into those pre-restoration La Scalas in the truck stop parking lot does not qualify as "a good listening session." Someday we'll have to do it right. See you at Picky's?


  3. "I guess I am trying to achive a starting point. Get it to sound like factory and modify from there..."

    That's the approach I would take. How about inverting the factory unit on top of the project? Then use only the bass bin (sealed at the top of the doghouse and connected to the factory network) of the project to see if the bass sounds like the factory units. If it doesn't, then figure out how and why the project bass bin differs from the factory. If the project bass sounds the same, then change variables, e.g., ports, networks, Crites tweeters, etc., one at a time to evaluate each change.


  4. Corey-

    Have you ever listened to La Scalas? There will be no comparsion to the "little Dynaudios." If you've never listened to La Scalas, paying a premium price might be a mistake. I like them, Craig likes them, but they're not everyone's cup of tea.

    Hi Diz! What would you say the main differences are, besides the La Scala's being "bigger" sounding? Are the La Scalas not as accurate or flat? Are they more or less musical than the Dyn's? I know this is tough because I haven't heard them myself yet.

    Corey-

    It's difficult to verbally compare the two speakers. As Allan says, it's apples and oranges. Nevertheless, with quality amplification and source material the La Scalas (IMO) sound closer to live music than the Dynaudios ever will. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    As to why Craig and I consider $1,500 to be at the high end of the market, its because weve each purchased La Scalas for considerably less. Would you get $1,500 of enjoyment? Certainly, if you like the sound of La Scalas. As you initially pointed out, Las Scalas often sell for less, but that doesnt mean that these arent worth $1,500, or even more.

    I would never spend $1,500 for speakers that I didn't KNOW that I would enjoy listening to for years to come, unless I knew that I could unload them without taking a loss.

  6. If the condition is very good, then $1,500 is fair, albeit toward the high end. You're correct about the advantages (monetary and damage avoidance) of eliminating shipping.

    If they look and play great and you keep them for years, the fact that you might have saved a few hundred dollars will mean nothing. On the other hand, if you decide that they're not what you want, it could be difficult to quickly sell them for $1,500.

    It wouldn't hurt to offer $1,200 and see what happens.

    EDIT: Craig-

    You're a fast typer. Great minds think alike.


  7. I should have made it clear that I'm considering doing this myself. I'd NEVER pay $200 to have this done to a $50 eBay receiver.

    OK, I'll confess ignorance. My B+K Tool muiltimeter can measure capacitance. Is that not in some way potentially useful in determining the health of the existing capacitors?


  8. Who has experience refreshing the capacitors in the ubiquitous H/K X30 series receiversor other SS receivers? Is there a way to test (in any meaningful way) the existing caps using only a DMM?

    <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    As many here might recall, I have two H/K 430s and I supplied an H/K730 to the local high school band to power the La Scalas I restored for them. It would be interesting to refresh one of the 430s to see if its worth the time and expense. A copy of the 430 technical manual is attached.


  9. Of course you're correct about the need to preserve recordings of vintage performances. There was a feature recently on NPR about how copyright laws actually hinder that goal. It's commercially impractical to legally record and exchange many recordings protected by copyright.

    What do you think Edward Kennedy Ellington would have thought of Bobby Sherman?


  10. My 15-year-old son listens to sports radio constantly on his Sony Walkman radio (hi-fi is not the issue). He breaks the headphones/ear-buds on a regular basis. Headphones break where they attach to the headband and headphones and ear-buds fail at the plug. Repairing those delicate wires is impractical. The expensive ones last no longer than the cheap ones.

    <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    Does anyone have experience with ear-buds and/or headphones that are more robust? Conversely, are there brands that are known for being unreasonably fragile? Perhaps the only solution is to buy a gross of cheap ones and replace as needed.


  11. When I started the thread requesting beater networks so that I could cannibalize them for their autotransformers[1] I never expected the pristine specimens sent by forum member lost_at_c. The generosity of the members of this forum never ceases to amaze me. Now the kids in the Birmingham Seaholm High School band will have the opportunity to experience their La Scalas with upgraded networks.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />


  12. Glenn,

    I'm looking forward to seeing and hearing the Eico and the H-IIIs; you and Verna too. Craig's VRDs would be a welcomed bonus.

    Inviting the neighbors is a good idea. With the Eico and the H-IIIs you'll be be able to drown out the conversations at Dunleavey's. Craig's VRDs would expand your circle of influence into Monroe County.


  13. Now you've done it. You've convinced me to not waste the time or money on this mod.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    My appreciation of the bass produced by La Scalas and Khorns is similar to your own. I'll gladly trade quantity for quality. If it were possible to get more bass extension from La Scalas without losing the quality of what's there originally, that would be great. Alas, there's no free lunch.

    Please understand that I love the sound of Cornwalls, but I wouldn't want to sacrifice the tight bass of the La Scalas to get Cornwall-like bass.

    To some degree the same holds true for Khorns. Many speakers go lower, but precious few sound as good doing so. Many years ago I used 4 Speakerlab SKhorns in a mobile DJ business. The bass from them when driven by a Dynaco ST-400 was very tight. One person called to book a return engagement and wanted to know if the price quoted included the drummer. She was convinced that there had been a live drummer.

    Thanks for the details. I would have done essentially the same and, I expect, reached the same conclusion.


  14. In the interest of full disclosure, apparently this issue did make "a dime's worth of difference" to PWK.

    Bob Crites mentioned to me that the screw Klipsch typically used through the air core inductors should have been brass. He was surprised to learn that they were mild steel, but said that sometimes it happened. He then suggested brass or stainless; anything that would not attract a magnet. I already had stainless screws that worked, so a trip to the hardware store to buy brass screws seemed unnecessary.

    You're correct that stainless screws were not used for cosmetic purposes. It would take a lot more than a few fancy screws to make those networks look pretty.


  15. Those are the GE caps that Bob sells, just like the ones he sent for my son's Type E networks. You won't be disappointed dealing with Bob.

    BTW after the "after" photo was taken I moved the caps farther away from the air core inductors. The original screws holding down the air core inductors were steel. At Bob's suggestion I replaced the steel screws with stainless, so as to not affect the air core inductors.


  16. Your impressions regarding the bass mod are very interesting. As I'm considering the same bass mod for La Scalas, I'd like to put your impressions in perspective. Others have repeatedly said that no one who tried the similar mod went back to unmodified. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    Please understand that I'm not discrediting your opinion; you can't be wrong when stating personal preferences. Nonetheless, please provide the details of your modification, e.g., port length, port diameter, stuffing, etc. so that apples can be compared to apples, as much as possible, under the circumstances.

    Like Craig, Im not surprised that you feel the attributes of the horn loaded bass are compromised by the bass reflex loadingand unloading of the woofer. Its all about compromise.

    Because its a relatively simple and totally reversible mod, Ill probably do it regardless. Even so, it would be useful to know exactly how you did it so that comparisons could be made to the ways that others have done it.

    Its refreshing to hear someone acknowledge that the results their latest DIY mod were less than expected. Thanks for your candor.
