    I sanded the fuse holders on the speakers then cleaned them off with a some mass air flow sensor cleaner I had in the garage. Replaced all the fuses and we are up and running.

    Something to note, i was not super impressed with the imaging of these RS. I just figured it was the caps. But after replacing the fuses I did not toe them back in nearly as much. They are almost at zero toe-in and the imaging just popped right into place.

    Some pretty big value caps. Be patient and hopefully a good cap sale will come your way.

    Does anyone know what the exact values are on the 1600 and 600 uf caps are. I'm trying to find out the voltage so I can make sure I get the right specs.


    I was trying to find Nichicon gold tune caps but voltages are all over the place. I've never had such a hard time trying to find caps. Uuuuggggh!

    No I don't but I found the schematic for the crossover in the RS IIa/b, which *may* be of some interest. It's interesting that there are 3 tweeters and they each seem to use 1.25 amp fuses. The high midrange uses a 2.5 amp fuse and the low midrange uses none (?). Total of 4 fuses.

    Since these are Di-pole speakers ( i think that's the right term, there is a tweeter facing the rear) should I be worried about the acoustic treatments in the corners as seen in my photos? It's just some acoustic foam and the larger peices are Acurelex Bass Traps.


    Should I maybe raise them up to about a 45 degree angle from the tweeters on the back?

    Unless the rear facing tweeters are firing in reverse phase with the fronts, they would be called BIpoles actually and not DIpoles.

    No Infinity Bass Contour Module included, which is a necessary part and was never an option. Amazing how many of these are missing that! They look fantastic though! I think the guy says he removed the grill pegs but he has the grills! I wouldn't want to use them but why remove the pegs and fill the holes lol?

    So.... I think I really screwed up today.

    The screens that came with these RSII were a bit smelly and I had been in the garage spraying the fronts with Fabreeze. I set the bottle down to turn the screens over, I then picked up the bottle i thought was Febreze and started spraying the back sides. Turns out i picked up a bottle of RainX windshield cleaner. I had a good 4 to 5 sprays each screen before I realized my mistake. I dont see any bleaching effects. All looks ok. I guess I'll have to wait and see what happens.

    Well SOB! GD porch pirates strike! God help one of them if i ever catch them in the act on my property. So the box of items that included a can of deoxit must have been taken from my porch.

    Does anyone know if any places like Lowes , Home Depot, Ace or others carry something that does the same thing? I have no Radio Shacks near me. I cant find deoxit locally.

    I did notice the auto parts stores carry CRC contact cleaners and other electrical cleaners. Will these products work for cleaning pots?

    Sorry to hear of that. Yes. Contact cleaner will work okay. DeOxit is just the "go-to" for audio.

    A long time ago in a far away forum one of my tunerinfo folks had a transmission fluid concoction that was alluded to work just as well as deoxit. Swore deoxit to have transmission fluid in it.

    I could see something like that working based on the properties of ATF. I'm not brave enough to try that **** out. Lol

    From the Michael Percy catalog, apparently you need to be careful and use the right stuff if you have carbon or plastic pots vs all metal ones. Apparently also the base solvent is purified naptha. There is one formula of DeOxit that has much higher capacity to clean heavily oxidized pots as well:

    Thanks again Garden. This stuff is safe for all plastics. I'll hold a rag to catch excess drippings. Just going to do a few light applications into the pots. After the first spray I'll let them sit a min or two then flush some more and work the pots back and forth then another flush. I'll repeat as necessary until the pots stop scratching the sound so much. Going to re clean the fuse contacts and the speaker terminal contacts where my banana plugs go in.

    I may also start with once driver at a time (as to not mess up the wiring assignments) and clear the Male and female ends at each driver. I'll use a dental pick to clean the female spades. Then spray them.

    I pulled the crossover boards out to have a look and clean the pots. Plenty of suprises for sure. My right speaker has a 3.0 ohm load at the terminals. The left has a 3.5 ohm load. Someone has certainly been inside these. Both crossovers are different. It appears the right speaker has undergone some work. Some one also disconnected the 1,600 if caps in both speakers. The right speaker has a pile of smaller caps for the 1600 but its disconnected. The left only has one huge cap for the 1600 and again its disconnected.

    And should all these inductors be offset from each other? Not so close and in the same orientation???

    Well take a look at the pics.

    Looking at this schematic it looks like the 1600 if cap is to cross the top woofer over at 125hz and the bottom to 50 or 60hz?

    I tried to remove the woofers to test thier resistance, but they are damn sure stuck in there. I will tap the uppers out from the back. The lowers are going to have to be pryed out.

    I'm thinking maybe the 3 *transformers* are perhaps laminated iron core inductors (or something)?

    I see 7 inductors but the schematic shows 8. Probably a small one hidden in there somewhere.

    Could this be it? Looks like a small iron core.
