B&W 802 Series 80 repair
Saw this B&W answer in one of the FAQs at the support site: We usually find that customers who alter crossover components are not fully satisfied with the results. They find that some aspects are improved, but others made worse. A classic case of this is when a polypropylene or other very low-loss type substitutes an electrolytic capacitor. We all know that polypropylene capacitors can sound inherently better, but the change in internal losses changes the response of the filter, which is designed assuming the losses of the electrolytic component. What usually happens when the low loss component is fitted is that the corners of the roll-off are sharpened, giving a peak in the combined response that can make the sound unpleasant in various ways depending on the crossover frequency. One way of getting round this is to wire a small resistor in series with the capacitor to approximate the original losses. I say approximate because the loss factor is a frequency dependent resistance. The actual value you need depends on the original capacitor loss factor and its capacitance value. The larger the value, the lower the resistance for a given loss factor. The formula for the equivalent resistance is: R = d / 2

I suspect that's at least one thing that could be going on. In terms of the crossovers, considering my relative lack of DIY skill, should I just pick the exact same values for the caps but maybe go with a different brand, if indeed they should be replaced at all?

If the wires shorted in that way, would they possibly blow the fuse on the amp?

I found this on the above website. Does it make sense to you wise ones? http://www.bwgroup-support.com/downloads/techmanuals/bw/802-TM.pdf

I should have gotten one of those. Unfortunately, that ship has sailed.

There's no power supply, true, but there is some protection circuit that has a battery in it--the speakers have small LEDs on the front. I think that's probably kaput at this point and have read elsewhere that it makes sense to just disconnect it.

If someone would just buy the Dodson... But if another computer shows up in my apartment, I'll need to sell a lot more than just the DAC to fund the alimony payments.

I've read that replacing the caps on these is pretty easy. But you are, of course, correct; depends on getting them open. Yeah, all of the contacts in the system could use a nice cleaning. Is that Caig Deoxit stuff worth it, or is it so much snake oil?

Hard to tell, actually. According to my Dad, at some point the speakers caused the amp to blow a fuse. Is that possible? I also think the right speaker cuts in and out. Finally, the binding posts are old and dirty, so actually getting them hooked up right now is difficult if not impossible. I'm not sure how the current posts ever worked in the first place to be honest.

B&W 802 Series 80 repair
My parents have an old pair of B&W 802 Series 80 speakers. I've read that these are still considered pretty decent, but I'm concerned about the condition these are in. I'd like to replace parts like the binding posts and maybe parts of the crossovers. How difficult is this type of thing? Could an advanced beginner DIYer do it? The speakers look like this (these aren't the actual speakers):
