Yeah, they sure went nuts with that adhesive! I'm currently rebuilding two Time Window 1A crossovers which I will be mounting in shadowboxes so you can admire the engineering. The thing is, I have to use the original inductor coils because I think they were hand wound. It would be impossible to find ones off the shelf that would match exactly. But, man, that glue! Fortunately, the 1A crossovers aren't as crowded as the TF-700s were. It pops right off with a knife. I guess they saved a lot of labor by gluing every damn thing together (which they couldn't really do with the backs of the 700s), but it sure makes DCM speakers a PAIN to work on. Again, thanks for uploading this! :)
Hello OldTechFan: What sonically changed with the capacitor upgrade? What is the "best" capacitor to use for the "best" change/upgrade? I see people use Russian paper-and-oil caps is guitars and guitar amps, etc. There has to be a Holy Grail cap for speaker crossovers. Thank you in advance.
(4:17) It depends on what kind of driver it's connected to. If they used a different one later on that is probably what warranted the value change. Steve Eberbach and company pretty much flew by the seats of their pants back then, so it would be interesting to see if they swapped out a driver for a different one. Time Windows come to mind, when Phillips stopped making speaker drivers and they switched to Vifa (now Peerless/Tymphany). However, it's likely you won't notice such a small difference without actually measuring the frequency response, so it's all good. :) I had these exact speakers in the late 80s and even had the backs off. Very cool to see the inside again. Thanks for posting! :)
(2:45) You can also see one of the infamous DCM aluminum core inductor coils here. Seems that aluminum does indeed have some slight ferrous properties. Just enough that Steve E. and crew would use it when an air core wasn't enough, but an iron core would have been way too much.
Could you possibly send me a guide on how to replace the electrolytic caps. I just recently got some TF700's and wanted to get it recapped as it's been sitting for a long while in a studio. Thanks!@@HomeTheatre101
I love my TF600’s,they sound just flawlessly!
As mine do!
Love my 600's as well 🙂 they are weird and wonderful
I still have my DCM TF 600's I bought new in 92... They still Rock

Would any of those caps you changed affect tweeter performance? I just scooped a pair and already know the caps need changing.
Update: New electrolytic caps improved them drastically! ✅🍿

I have TF500's nice speakers
