DCM TF1000 schematics?

[Plomaman27]

Just wondering if anyone knows where i can find schematics for DCM TF1000's... i picked up a decent pair @ salvation army and found one of the woofers had a finger hole poked in it;-) Looking for suggestions 4 a good method to fix the hole OR a good replacement driver. Thanks in advance.

You are not loading us up with enough info. What is the material of the cone of the woofer? Paper is an easy fix, plastic maybe a bit more difficult but still doable. Then there is the bay that has DCM drivers floating in it all the time. Ones you can use will show up sooner or later. Or there is barter town where you can ask for them but you need to subscribe, 25 a year for all that good.

The woofer is a paper cone made by Carbonneau. You cannot find a drop in replacement. Your best bet is to repair the paper cone. There are a number of threads here or on Google that explain the process. Essentially some tissue paper, built up in many layers, with glue. It's like working with fiberglass but without the cancer.

The schematics will be harder to find, but there is a thread on the AVS forum called "Where in the World is Steve Eberbach" or some such. That thread may have schematics for the 1000 or the 700, I can't remember which.

For what it's worth, if you have the crossovers in there, you can just hunt and peck for replacement parts for what you need. They all have values marked on them except the inductors which were all custom made and hand wound at the DCM factory. The most common failure I have seen is that 2 ohm 5w resistor.

TF-1000's at the Salvation Army store... Congrats !
Repair the cone and enjoy those rare and exceptional speakers.

If you post a photo of the woofer damage it would help.

Thanks for the great ideas! I guess i should go with tissue paper and elmers. Wont it look like crapola though....black paper cone with white tissue... yikes! What the heck no one sees it. I'll keep checkin ebay for an 8" driver...meanwhile ill keep the socks pulled off. I'll post pics asap and update thruout the refurb... thank u for the schematics reverb those will help a whole lot guaranteed. One speaker is sounding pretty weak on the bass... i read in another thread to check out the old electrolytics as they tend to dry out inside. Looks like these babys need all new caps and ceramic resistors too. I found a loose coil (mid range) which was flopping around and managedntonpull onenofbthe leads loose... resoldered and got midbfreqs back.
