Well I suspect those Solens are not the oem caps. I seem to have a memory of seeing one on eBay years ago with yellow and or black/red caps. The ohm reading point toward the voice coils being good. So perhaps you are lucky and do have a xover issue. I would imagine a schematic is out there. Have a peek at the Yahoo group files.?
1) Some of the inductors are wound with fine wire, so be careful poking around.
2) None of the resistors looked fried
3) Nothing seems to be disconnected
4) There were manufacturing variations, so wire color and some components may be different than others' without destroying your belief in them being original. Though there weren't as many DQ-20i as something like the DQ-10, so probably fewer construction variations. FYI I have early DQ-10, late DQ-10, and DQ-20.
5) Things of this vintage were hand soldered, and nothing is perfect. If a solder joint separates it won't look it. If you are up to it, a gentle pull on each wire as it attaches to a soldering post (not as it goes in to a component) could find an improbable bad solder joint. If you are not comfortable with soldering don't do this, since if the connection comes off you won't be able to fix it
6) The capacitors with the stylized S logo are Solen, which is a good brand

Just because I haven't seen this posted anywhere, here is a pic of my high filter crossover. This pic is taken looking in through the hole left after taking the woofer out. There was a fair amount of insulation packed in there that I removed so I could see the crossover. I am assuming this is all original because the guy I bought them from said he was the original owner and never touched them.? Can anyone verify?
