Got this from the Berklee.edu website. Hope it helps.
For starters, the DVD-A supports LPCM in a wider range of sampling rate options: 44.1k, 48k, 88.2k, 96k, 176.4k, and 192k, at bit resolutions of 16, 20, and 24 bits. At the highest sampling rate and resolution, this yields a theoretical audio performance of 96k bandwidth and 144dB of dynamic range! Note that there are now supported sample rates that are integer multiples of the current CD standard of 44.1k. This makes it easier to record a project at, say, twice that rate (88.2k), and do a simple downsampling to 44.1k for CD release, whereas downsampling from 96k to 44.1k is a more complex process with potentially greater loss in sonic quality. As in the DVD-V format, the DVD-A format supports bit resolutions up to 24 bits. However, unlike the DVD-V spec, the DVD-A has no lossy data compression schemes as a mandatory consideration, although provisions have been made to utilize them as options.
You can see the whole article here:

With the driver attached to the LPAD, use your meter across the input terminals (what would be coming from the amp). You should see the resistance stay the same as you adjust the slider. Make sure you have no power on (actually, disconnect the speaker from the amp). I could send a drawing if you need it.

Gil,
I at first thought the colors were kinda pukey, but he is my son. I'm just impressed with the drawing of the player itself. This is a good sign that the money for this education will pay off someday.
So what do you think of some of the color schemes that Klipsch has had for their web page?

Justin,
The web site design you did looks nice. It loads pretty quickly. SOmething dial up folk can like. Some sitesa re pokey even when using broadband. I tend to like the les is more design philosophy.

Okay, it is a low rent amp, but someone has to have some idea here. The worst part is the output transformers are NOT very big (very little iron).
I just acquired (for free) an old Knight Kit (Allied Electronics) tube amp, and need some help finding a schematic for it. Okay, maybe I don't really need a schematic, but they are always nice to have. The model is a KN928, and it has four 12AX7 preamp tubes and four EL84 output tubes. Anybody willing to guess what the output poewr of this might be? I'm guessing maybe ten tp fifteen watts per channel. I don't really know the EL84s that much. The amp is pretty clean, and has been stored inside. Not like someone putting it out in the barn for a few years. It is missing one of the EL84s, so at least one of those is in order. The EL84s are GE and the 12AX7s are Amperex (one is a Sylvania). A Raytheon 6CA4 for the rectifier.
The chassis has more steel in it than most new cars. The wiring job was fairly neat, but the layout sure isn't what you would find in newer tube amps, where there is more physical symmetry. I'll have to get my variac out, dig out my meter and check it out. It looks like it will need less work than my Dynaco, as I haven't replaced the 7199 tubes with a different set of parts yet.
I figure this might have been based on a reasonably good design. Then again, maybe it should just be tossed. I hated to pass it up.

Not being from the other side of the pond, someone on the Steinberg/Cubase forum said it means a "masturbator."

The Pi speakers are more of a scoop than a folded horn. I have a bunch of different LS drawings that I got off the net before. I would be happy to email them to you. It will cost you more than buying a pair from someone.
DJK built many pairs in the past. With modds and all. Some for P.A. use and some for HiFi use.
I still haven't done it, still don't have the time or money, really don't have the room. A pair of Heresys however ....
John,
Hope all is well with you. Things are too busy up at the college to get involved in much.

With MY budget, I'm not going to swap out my zip cord any day soon. I just want to add to my speaker collection first.
Hope Invidiosulus is feeling better today?

I can't believe I actually own some of this stuff. Not the higher priced articles though. I still have a Dynaco ST-70 (still awaiting a rebuild), and the Sennheiser HD-414 headphones. I still have three pair of those. I got them after doing studio work in the '60s, and loved them. The drivers on at least one pair are blown, but I can't seem to part with them.
The DAL audio card is very good, although M-Audio gear is way cheaper and the converters are probably as good sounding. My daughter is still getting to use a Nagra at school as she does soundtracks for film class. I'm starting to feel old now. The Revox machines were to die for when I was getting into recording.

Upset. Of course not. Only that he has the speakers in Florida while I am here in North Georgia. I can't even convince him to let me have the JBLs (which are about 30 years old) to use as MY rear speakers. Actually, I'm impressed that he pulled it off.
I am glad I brought him up to know what good speakers are really like. I've just about decided that I should find some Heresy pairs for myself. They would be cheaper that the LS and take up much less room.

My son just got a set of Heresy I speakers (2) off of Ebay for about $300! I send him of to school and this is how he shows me respect?
He got the bid with 13 seconds to go. He says they sound absolutely wonderful. Little dings on the back, top corners. They are black, circa '81.
I suppose he will now use the old JBLs for rears, but he hasn't told me yet. I had to put my building of LaScalas on hold, to send him away to school and then he does this to me!
Hope you enjoy yours when you get them.

If you know anyone with ties to ham radio, or go to hamfests, you might still be able to pick up tubes there. I just looked at an old piece of Tektronix stuff our college had thrown out (my son brought it home, and it now collects dust in his room!). It has some GE tubes and one Telefunken 12AT7. They threw more away this summer, but I didn't get a chance to go through it much. Picked up a Heathkit, tube bench supply, and a Heathkit audio signal generator, also tubed.
Way cool. Not sure how it fits in with all my digital audio recording gear.

Mallett,
I agree that there is a price diff. Their price as a kit (which is supposed to be easy), isn't too bad. My own, as yet not upgraded, ST70, I purchased for $50, and have also had for over 25 years. I'll probably go with the Triode Electronics upgrades for it, and they are not very expensive. (Some would also say not as good as the AVA upgrades) I just don't want it to blow up form old caps that are dried out, etc.
I bought mine from an acquaintance in the early '70s, and just this past Spring, started going over the schematic and instruction book. I found he had actually wired part of it wrong. I checked it, double, triple checked it. It really was wrong. I changed it, and is has made now difference in the sound. It needs a lot, and is too noisy to use right now.

If you want to spend that kind of money, check out the Sound Values NEW model of the ST-70. Very cool!

You may find the parts you need for Dynacos at Triode Electronics:

I have an ST-70 that I STILL need to get upgraded. hey have replacement cap boards that will fit inside the ST-70 chassis, and other tube mods, mostly to replace the 7199 with a better tube. They also have the schematic on their site.

Wow! I have a pair of JBL 4311s, from around '72 and they don't have foam surrounds in them. They still sound awesome. I still use them to mix with.

Junior Brown! What a hoot to hear him play! Have photos of Gary Richrath while we were just out of hish school. Haven't heard him in years.
How about (acoustic music):
Phil Keaggy (acoustic or electric)
Tony Rice
Bela Fleck (okay, he plays banjo, but it doesn't sound like it)
Victor Wooten (plays more notes on a bass than most people can play dropping a load of ball bearings on an open piano)
This list could get VERY long, but I have to go.
New, younger musicians have the advantage of learning and hearing more music than ever before.

Mike,
If you mean that MS puts cookies on that won't let you use unregistered versions of their own software, I don't think it's true. XP Pro is probably the most stable OS they have come up with yet. Other than the little registration thing they make you go through (which takes all of about three minutes), it isn't that big a deal. I still use Win2K, although my son has XP Pro and Lightwave 7.0 (registered) on it. It works very well, and handles IRQs much better than 98se, ME. I only use Win2K because of driver availability for some of my audio hardware.
Maybe they will end up switching to a dongle like Cubase and Lightwave, and others.

You can also get a beeswax oil, and wipe on with a soft rag. Put it on over the stain. It makes a gorgeous finish on good wood. Very matte. Very easy to apply.

HII,
The ASL equipment is made overseas (not necessarily a bad thing.) If you want the power and like the EL34 PP design, the VTA 70i, by Sound Valves (designed and made in the US), is $900 for a kit or $1k wired. I used a 30 wpc tube amp on my JBL 4311 speakers, and they would crank quite well. Had a very nice sound.

Ray,
How are things in your neck of the woods these days? Are you back to work or are things still off for you?
You may have posted this earlier, but I/ve been on to other projects for a while. The LS project is on hold while I spend money on other things (just built a dual Athlon 1.4 Ghz w/768 M ram -- smokin' fast).

It partly depends on the thickness of the wall material. If you go to the 3M site, you can do some research there. Different kinds are made to different MIL Specs, fulfilling different needs. Are you worried about high voltage arcing through the material, or how it will change the capacitance on a cable?

I love my ST70, but a NEW, updated model is available from SoundValves:

They had bought all the old Dynaco stock. They build this one, right here is the US.

Jake,
Look under the thread on troubleshooting and find the post started by Chris Robinson. Lots of thoughts about ventilating cabinets.

I'm very curious about the chroming on the transformers. I was showing the pics to a friend of mine. He agreed they are a work of art. He thought it was odd though, because he said the chrome will work as an insulator. He is a vintage VW buff, and said folks who chrome the valve covers on their VWs see a 30 degree rise in engine temp. I would hate to see the trannies get to hot. Don't see many chrome wood stoves either.
But they look soooo coool!
