The pic I showed already had the cap replaced. I should have posted a pic of the bad cap. It was rather obvious who the culprit was. I would have a harder time with many of the other components on these guys, as they are mostly surface mount. I have replaced surface mount parts before, but it is a little tricky with my small iron I use. It is low voltage and pretty low current, so the small connector itself isn't that much of a problem.The Neutriks for POWER are the bright blue, and called Powercons instead of Speakons. This is to help keep people from plugging power into their speakers. [:|] I used to diagnose and work on 3 phase motor controllers for the textile industry. EDIT: Looks like I'll have to be taking it apart after all. The mutes are acting up. Could be they've been messed with too much, but it may be part of the mute circuit that is causing them to mute at inopportune times. Probably something in the circuit as I can't believe all 16 mute buttons are messed up.

I realize you added the tube rectification, but what was the major omission? You mean different than what is posted on the website?Bruce

You'll probably be taking orders for Greg... [Y] What will you pair those with?

How's things in Earlville? I'm still enjoying the LS! Nothing but compliments when folks hear them. Getting the AL crossovers changed out helped a lot, though. Those EVs would be wonderful! Bruce

My speakers are only 6 1/2 feet apart (center to center), with 2 feet more on each side of the room. I actually get a wider soundstage that way, compared to having them farther apart.I sit a little over 10 feet back. Well, I'm not too embarrassed. I'm going to listen to those tracks again. I'll see if I still think your recording sounds sterile [*-)] btw, I bumped the original challenge so folks wouldn't have to hunt for it... Bruce

Just to bump this in case someone needs to re-read their posts. [Y]

Thanks, Don. ALL I can find wrong with the LX7 is one knob missing, and one other rotary pot (for the talkback level feels a little wiggly, but it still works fine and there is no noise from it. I think this boils down to... It's old, and newer is better... I haven't read the manual to learn how it really works so it sounds like cr@p... I really want to get some newer toys in here. One of the students who works for this av guy told me that the mic preamps were worn out. I almost couldn't keep a straight face. The input gain controls are fine. He said they had to turn the controls all the way up to get enough gain out of the wireless mic's. Perhaps they could have also adjusted the output of the receivers, but I wasn't going to tell him that. This is the same guy who said that the silk dome on his tweeters covered the actual diaphragm [*-)] and that tube mic's work by the vibration of an element in the tube. [:#] Whew! Some stuff he does really well, and his mixes are usually fine, but his actual understanding of how this stuff works just baffles me sometimes. Now... if I could just find a Fostex E-16 for the same price and in as good a shape, that would be cool.

Nice, Mike...[:|]

Are all the plies oak? A question for dtel. Not all veneered plywood is the same all the way through. The interior plys are often made of other woods.Baltic Birch is all baltic birch, for instance.

How's your back?

Does the Emotiva gear get a couple hits for being a TN company with all the gear made in China? [*-)] Just kidding, it IS great equipment. Bruce

Are all those oak? A lot of plywood uses birch or poplar for the inner plies. Bruce

I have some Galaxy Audio 5 inch drivers (used in the Hotspot monitors) and have contemplated using one for a mid driver for my LaScalas. They ae rated 200-18k. What is the eff. of your Audax? Looking good, btw. Bruce

Dee, There was a percieved loss of clarity when the driver/horn was moved toward the front of the cabinet. I thought there might be (probably are) some detrimental effects caused by reflections off the top of the LS cabinet, but the closer time alignment of the K55 with the APT driver ore than make up for it. The up mid to highs are a lot tighter. The larger horn on the tweeter is better, too. With the tweeter at the back of the cabinet, I tried carpet, foam, and other materials to see if I could hear a difference. I couldn't, so I'm back to the good looks of the tops. [Y] Bruce

Troublemaker...[]

The LX7 got replaced by an A&H PA series for th eroom where the drama dept. has productions and a Mackie 1604 was replaced with a GL2200 24 input went into our chapel. The chapel gets used for other shows and larger performances. It's an asymetrical cavern that seats about 800 (not sure exactly what the seating is).The Allen & Heath equipment is pretty nice. We still have a 32 input Yamaha in a case somewhere. New hires seem to always want something else, insead of learning how something works. I plugged the LX7 into my system with the LaScalas last night. With all the input gains up, all faders at 0, routers to one of th eoutput groups, sitting on my couch I can't tell it's on. Newer gear should be even quieter. Missing one knob and the pot for the talkback level feels loose.The Spirit SX is just as quiet.

Mike, if you look at the first page pics, you can see the vertical flare.

I'm just glad you survived your week.

Especially since she likes the Macs...

I haven't seen anbody building any like this. It took me a while as I don't have any kind of workshop, so I waited until the deck was dry and cut and routed outside. [] Are you making a tractrix for the tweeter by any chance?

From the back... I have the mid and tweeter lined up.

jc, This is what I did for my APT150s, which uses the same driver as the the CT125. Bruce

Those horns in white would just disappear in your corners...[:|]

Interesting... I went and measured mine, and came up with 16 11/16. Another 1/16 bigger wouldn't hurt. I wouldn't have measured mine, but I first looked at the pdf drawwings that Jim E. did. He shows 16 3/16, which is too small. I think I'll edit the pdf and correct it.Bruce

PT, Thanks! I'm not sure the connection is a design flaw or student workers abusing it. Although I have some mic cables I made over 20 years ago that still look new, and I used them all the time. I just didn't let anyone else coil them up at the end of a gig. They could be Alps faders. Definitely 100mm, which is a plus. Our A/V guy at work hated them, but it certainly makes it easier to move a group of them at one time (if they aren't feeding a sub group, of course). They are very smooth. I should have paid more attention to them when I had it opened up. I'm not too inclined to pull off all the knobs and remove the screws again if I don't need to. [:|] It's really quiet. It would be a pain to service with the single board and surface mount ICs. Bruce
