Pet Sounds - The Beach Boys on my BM 4500 with a freshly rebuilt set of RL 60's.
-
Unfortunately when I received my RL60's not only were the ABR's rotted but the plates were missing altogether. So my solution was a complete passive radiator refit that I learned about reading back threads on this site. I just finished the refit including rebuilt crossovers and installing new fabric to replace the old tattered and faded cloth

I got the blowtorch out and was able to pull all of the resistors out. An up close inspection under the light revealls clearly that the burnt resistor is a 10r 10% resistor. That said I can get non inductive 10W Munsford resistors that will match up all 4 precisely.
-
Like I said under direct lighting I could make out the markings that looked like 10R at 10%. doesnt appear to be any spacing between the 1 and 0 where a comma would go. Make probably more sense if I add up values assuming my crispy critter is a 10 ohm resistor. I come up with a sum value of 39.8 ohm spread accross the board, which is more in line with

I was thinking Mills non-inductive resistors At 12 watts, I can also get Munfords at 10 watts. All at 1% tolerances. As far as caps go I found Clarity at 250VDC or Janztens at 400VDC (Cheaper). and also some super cheap 100 v caps. What I see on my board is a total of 4 resistors and 4 capacitirs. The burned one is probably a 1,0 & 10% a 6R8 (6

Thanks it does in fact match I was able to put the cross under direct light and using a Magnifying glass amke out 10r & 10%

The other cross has the exact same problem. Waht is specifically need is the resistance values on the burned one. The B&O spec says 15 ohm @3 Watts, but it also tells me to replace my caps with 23 volt caps. That aint right ! All Radio shack does anymore is sell overpriced cell phones and ipods. what little stock of parts they do carry are overpriced
-
Pulled this out of a RL 60.2. Just got the speakers the other day. Knew something wasnt right. Could only produce about about half the sound of my other set of 60's. So what are the recommended caps and resistors for replacement and where from. Thanks! I live in the US I looked at the specs in the service manual I downloaded but am unsure. A lot
-
Thanks Martin, that is pretty much how I thought it was, but I thought I would ask anyways. When my next set of Red Lines arrives I can set about to replace the old busted ABR's in my current set with passive radiators. I am looking forward to running the 2400 next to the 3000 and see for myself.

After reading the rave reviews over the past several months from you seasoned Beoworlders I had no choice but to drink the Kool-Aid and go out and buy one of those things. My question revolves around speaker impedances I have 8 Ohm RL 60's. The specs state speaker impedence at 4-8 ohm. However I notice most of you fans of the 2400 typically prefer
