Klipsch Chorus II Restoration

Thanks for the kind words Dingman. The actually look much better than the pictures reveal. I desperately need to get a better camera.

Standing invitation for an audition if you ever find yourself in Middle Georgia.

Beer's on me! :beer:
 
Thanks RS Steve. It was a lot of fun.

They are being driven by my Scott 299B right now and you are correct, they sound GREAT on tubes.

As others have chimed in with, Congratulations! Feels good, huh?

What's next?

It does feel good in some respects... the spots that I dorked-up mock me however. I know most folks would not notice them but they yell out at me each time I walk by. I do believe they could use one more coat of Danish Oil as well. I think I can do that while they are in the house. A little cardboard underneath and it should be good to go.

On the plus side, the wife has made nothing but positive comments about them since they found their way into the house. We ate dinner tonight while listening to Billy Joel - The Stranger. She commented how nice piano sounds on them - and she's right.

What's next???? Not sure.

I am in the process of trying to re-veneer a Pioneer SX-880 case. Boy, do I ever suck at veneering! I'll post a couple of pics when it's finished so we can all have a good laugh.

Thanks for your advice along the way. Your guidance helped make them turn out better than they would have otherwise. :thmbsp:
 
You're absolutely welcome! Don't danish oil inside, fumey. Bad idea. I was going to mention any mistakes you see, don't sweat it. Everyone has those, no matter how minute. Take notes of what you see and how you would repair these and how you would bypass that issue for your next project. I've got the same "mistakes" on all my projects, ones that only I will find. Or another AK'er would find, we're good at that.

The only time you should give yourself a hard time, is if your ensuing projects have all the same mistakes.

I love how these rehab projects are so well documented, I've learned a lot and have more confidence in what I'm doing ( or contemplating doing ) having seen it done.

Reverb, thank you for sharing, mistakes and all. Me, I always end up making All New & Improved Mistakes.

My pleasure Mark. Glad you found the thread to be of use of what to do (and often, what NOT to do).

I'm sure I will make new and improved mistakes also next time around too. If you aren't making mistakes however, you're likely not learning much either.
 
Not much more I can add, but a JOB WELL DONE!

I also greatly enjoy reviewing these projects and outcome. It just never gets old. At some point, I too hope to find some Klipsch's for a tube pairing.

Thanks Audio Fan. I too enjoy these rebuild threads. Now if only someone would do a "Rebuilding your Scott 299B for Dummies" thread I would be set!

I spent a great deal of time in my misguided youth up in your area. Moved to GA about 15 years ago but born and raised in Gaffney SC.

We would hit Charlotte every weekend for the midnight movies - then down Trade Street to Bojangles about 3AM to take care of the munchies. No telling how many times I have seen "Song Remains the Same", "The Wall", "Rocky Horror" and "The Warriors". Good times!

:smoke:

Best recap that puppy (and check all your power / bias resistors) ASAP before you have a very expensive magic smoke event.

(seriously, if you toast an output transformer, you'll be crying in your beer)

Took your advice derek. I am not capable of performing the work myself so it will soon be winging it's way to Craig at NOS Valves for a full electrical rebuild.

I'll try to learn about tubes on something a little less valuable.
 
Really great job on these! Having just completed a re-veneer on some Quartets, I can imagine the effort involved in turning, flipping, and lugging the big brothers...much respect for your effort.

Thanks agolfman. They are quite bulky to say the least. Once you remove the 20+ lbs woofer, moving them around becomes much easier :D
 
The Payoff: Sonic Nirvana

UPDATE: The Scott 299B has been completely rebuilt by Craig at NOS Values and is now paired with the rebuilt Klipsch Chorus II's.

What a sweet sounding system. Craig did an amazing job.

Left to do: Replace the OEM Chorus tweet diaphragms with Titanium's from Crites.

This will happen soon, but gotta save up a little "fun money" first.
 
Chorus Rebuild: Part Deux.

OK. Spoke to ("The Man") Mr. Crites tonight. A set of titanium diaphragms should be in the mail to me tomorrow.

Once they are here and the Chorus are back on the operating table, the single remaining electrolytic cap will be dealt with.

Not sure what I will be using as a replacement. The Crites crossover upgrade retains an electrolytic in the 68uf spot. I may do the same and run a nice film & foil bypass cap in parallel. Some say that a bypass cap is fools-gold (including Mr Crites) but they are used in many JBL crossovers and you would think they know a thing or two about speaker design.

Except for some additional cab stuffing moray james spoke of in the Klipsch Korner, I think that's about as far as I can take these baby's.

They sound awfully sweet now. This will just take them to the next level! :music:
 
Hey,

My 222c is supposed to hit Craig's operating table today! Neat, huh?

If you're using a film and foil cap to bypass a film and foil cap, they cancel each other out. Fools gold and a waste of money. If you use a film n foil cap to bypass a non-polarized electrolytic, good stuff. I got this information from my friend, Mr. Crazy Scientist Man.

xo, Biggles
 
Yeah, a film & foil parallel to a non polar electrolytic is the plan.

I have a decent electrolytic 68uf and a .47 film & foil.

The ones that believe in by-pass caps say it adds the "sparkle" to the high end.

Not sure I can hear it at 52, but what the hell - I got 'em both so why not give it a shot.

Don't think a pure poly solution would fit in the space available.... it would be the size of a small poodle :)

btw: Craig a NOS Valves rocks! You will not be disappointed.
 
I just turned 50, my hearing is still pretty okay. I can most certainly still hear an improvement after recapping anything I've done so far.

Time for food.
