Ill get a notice in my email someones posted in this thread and before I read it, Im lookong up saying out loud ... The hells a guy gotta do to find a set in Dallas!? Big smiles for ya!

Thank you! No sir, I look almost every day, from coast to coast. Ive only ever seen a set one time like 4 years ago, down in Houston. Guy wanted 15 double oughts for them and at the time I though ... nah, Ill find a set closer for less. what was I thinking? But no matter ... a set will come by and Im always smiling at folks like you who manage ti find a set:beerchug:

Hah .. your the best Two Socks :beerchug: Couple of years ago, had a guy selling a really nice set in Arizona for $700. Took him a while to get them sold, just wasn't anyone near him interested. Can't tell you how many times at night I set myself asleep thinking of how I could drive out there and get those. I can't be for sure, but shortly after someone bought them, someone posted another CL ad in the same city, selling a set that looked pretty darn close to the other guy, for over three times the price. Eventually, those too were bought.

I'll get a set one of these days. They hold a nostalgic memory for me.

Side note, I fixed some of the spelling in my previous post. I make lots of mistakes posting from my phone from work (sorry).

Great amplifier for the 910!

I've collected a good number of vintage stereos, which I learned about on Audiokarma. Every one I bought my tech recapped. I wanted to hear them in top shape! I learned much from comparing and contrasting. I learned what a good vintage amp should sound like. I learned what a good modern amp ought to sound like.

I found that modern amp in the Yamaha A-S3200.

Lots of American and British audio magazines tend to favor "homemade" gear, which costs outrageous amounts of money, while belittling Japanese stereo manufacturers. My opinion, and my take right or wrong. I took a "chance" on a Yamaha integrated amplifier.

Wow! This unit is Ah-mazing!!!

I'm about halfway through the burnin, and it keeps amazing me. I have the Yammie connected to my 910's, which Richard So completely rebuilt (tweeters, mids, woofers, and crossover). Yamaha hit the sweet spot to my ears. Clarity and warmth are balanced and the sound is defined and smooth. The sound stage is huge and seems to appear magically from the wall. I lose the speakers, and the listening environment becomes a stage before me. Absolutely, no fatigue is present, and I listen to them from 5 to 9 every evening, except the weekend when my wife rules the entertainment schedule.

My two favorite vintage receivers prior were a Pioneer SX-1250, and NAD 3020. When I first heard those two, I was so impressed, and still love them, but the Yamaha does so much well. The Yammie is smoother than the 1250, and clearer than the NAD. I owned a Yamaha A-S1100 previously, although a lovely sounding integrated, it was a bit too "creamy smooth", and the vocals too far back for my liking.

The Yamaha A-S3200 is expensive, but I bought a new one for much less than the advertised price. I got lucky. I found a heavenly hifi, online business (I don't know if I can say where. Saying may violate a policy on this site?) in Milwaukee. I'm a vintage regular Joe with a budget and I saved up for a nice modern piece. I decided I couldn't afford the A-S3200, so I went for the previous model, A-S3000 at a discount. After paying, I got an email about an hour later asking if I wanted to upgrade to the A-S3200 for 10% more than the A-S3000! What! I could barely type my response, "Yes! Do it now!" I even followed up with a call to ensure they got my email response. I'm in heaven!

If you have a chance, buy the Yamaha A-S3200 to command your 910's, and you will NOT be disappointed!
 
Hello fellow 910ers! Anyone know where I can get LED meters? Also, can anyone post a clean straight on shot of the label for the LED meter? I'd like to make a set for myself, but need to create the artwork.

Thanks in advance!

Vintageaudio in Canada is where I got my LED power lights...I have no stickers either..
With the fresh crossovers these L910's are Incredible..
 
My father (who was VP Engineering from founding in 1972 until 1985) just went through a pair of my 910 crossovers, tested all the caps, and said he found them all to be within spec. All original. Even the large Mallory electrolytic, which are most likely to degrade. He then snapped a photo of the Crossover, labeled all the parts in the photo and drew me the schematic, which he then entered into PSpice simulation and plotted the crossover curves for me, including the multiple imaging switch settings.

So, your original 910s may not need to be re-capped, though it probably sets them up nice for another 40 years!

To follow up on this, I bought a spare set of recapped crossovers for my 910s last year at the Blue Mountain Lodge meet. I was all excited, couldn’t wait to make the swap. I did, and....., they sounded exactly the same! So two things, one, I was very disappointed, two, it proved how well made the originals are, with high quality components. So the originals are back in, and the 2nd set are spares for unobtainable parts if I ever need them. Nothing with recapping them, but for me, I wouldn’t do it, except for possibly replacing the lytics in the woofer circuit if the originals have drifted out of spec.

I think having them receive preventive maintenance is excellent, and certainly there is no one better (or better equipped) out there to do it than Richard So. Other than spending the $$, hard to see how you go wrong!

I modeled this label in Solidworks using a spare label I have for reference. The artwork was sketched over a photo image of the original, so it should be about as close to perfectly accurate as possible. It includes draft angles, as the original was cast somehow. The file may work with laser sintering rapid prototyping (SLS), but I do not know if the fine features will be resolved or lost. The lines that make up the 910 are only 0.010" wide. I have .STL and .STEP versions as well. Since I have read previously where Directed (DEi) has been contacted and was OK with replicas being manufactured as replacements, I imagine this shouldnt be a problem?
