time windows 3s recap in near future

scottyboy76

Just spoke with a gentleman from audiolab in atlanta, will be taking my newly acquired but not up to par dcm time windows 3s for a recapping, he quoted me a ballpark of 75 bucks for both speaks, plus caps.

Im hoping it brings that tw sound into these old boys, cant hurt a pair of speaks this old.

Any opinions on brand of caps or price quote is welcome, as i have never done this before, but im actually very excited to hear difference.

There is a great thread on avs forums, entitled "Whatever happened to Steve Eberbach".

On page 29 a gentleman named jamie hauser, who has done some incredible work on time windows has a list of his preferred caps for a redo of tw3s, they are by ERSE i believe.

I could order those,{IF I CAN FIGURE OUT WHAT THE HELL THE TERMINOLOGY IS], or audiolab sells, and almost surely has all parts needed.

Post the terms you don't know, questions you are looking for answers for, or a link to the page. I'm sure there are folks here who can help you.

Can you get a schematic of the crossover? That would help.

I have changed my allegiance from Sonicap to Clarity Caps as of late so I would suggest them. I have heard Erse as well and they do a much better job than the stock caps ever could so either should work fine.

Make sure they are using Poly's and not Electrolytics.

will use polys, and will try to link that page, not the most computer savvy.

I'll try to find that page later tonight and put a link up here for you scott...

thank youtn,
BTW will be pming you, wondering if dads bday has occured?

Just got back from radio shack, bought a spl meter, will be trying to download the frequency range test cd that jamie gave a link to over on avs forums, want to play with this and the tw3s, also, will be trying it out on our ht setup in bedroom.

as long as it remains in one place, the tripod setup is not mandatory, right?

Also, which works better with meters, the test tones from ht rec. or playing a movie, seems like test tones.

Have a lot to study up on, but im looking forward to my new toy.

This is one of the things i bought the spl meter to use with.

Do i have to use a music cd, or can i use a cdr, also, is any of these options allowing me to download all of these, or do i have to put each one on separately.

Trying to do this in order to check for bad drivers in my tw3s.

Thanks for any advice, im not computer savvy, but now that i know how to post links, get ready cp.

i just ordered the caps from erse, as per jamie hausers recommendation on avs forum,was wondering if, generally speaking, would you replace any resistors, inductors etc. if redoing a crossover.

This is not a complete overhaul, like the ones im sure many of you guys have done.

Just wondering if there are any select parts on older crossovers that you would automatically consider replacing, of course after the caps are dealt with.

Thanks in advance.

Depending on what kind and quality they are, the inductors could be replaced if you can find exact values (inductance and DCR). This may not be as critical if they used decent ones.

Resistors the same; replace with exact values unless you're trying to tune the sound of your speakers. If your Xovers have cheap sand cast resistors you could go with Mills. There are other brands out there that are also good, but I've used these in three Xover rebuilds with excellent results. They're only about $4 each.

I'd love to try the Dueland cast resistors that Quadzilla used in his 2.3TL rebuild, but they're a little too pricey for me ($50 each).

...You will luv the TW3's. I went thru the series back in the ole days. The 3'are the best. I loved the original TW's. Had them for many years. I used to bring them up to my Mountain house outside of Berkley Springs, W VA. I put them on our deck and then would walk thru the woods listening to some awesome tunes. I still have a pair a DCM QED's that still sound GREAT.

scottyboy76

That gives me hope, I think after selling gear and upgrading preamp, i will eventually get some 1as, just to have 3 of 4 models of tws.

That sounds pretty cool about walkin thru the woods listenin to tunes.

And drumminman, Since it will take weeks for repair shop to get around to my speaks(very popular shop, and one tech is out on medical leave), I will probably research parts, and send them to shop.

The charges are pretty reasonable for the caps replacement, so why not.

scottyboy76

Will be making the app. 2 hour trip to audiolab tomorrow to drop off these babys.

Im going to inquire about cost of replacing resistors also.

Im guessing its pretty easy to judge what to replace original resistors in speaks with?

This business also sells caps and other audio related replacement parts, so i figure they would stock suitable resistors.

I have the caps that were recommended on avs forum ordered and will be supplying technician with those.

If anyone has advice as to ins and outs of resistor qualitys, changes in sound etc.
any advice would be greatly appreciated.

Scott-
I'd go w/ mills on the resistors- they seem liked by most and are reasonable cost wise. As to the inductors I've never replaced any, but I would recommend talking to the Jamie guy whois the expert you mentioned and find out what values you have and order yourself instead of letting the shop order for you and charge you extra. I doubt they keep alot of inductors or resistors on hand and you are already supplying the other parts. Do your research while the guy is on sick leave and save yourself some $. Just my opinion.

scottyboy76

Got it, I have heard that name a lot around here.

Thinking i will talk to jamie, that guy is as good a record keeper as he is cabinet maker and electronics whiz.
