M100-2 crossover capacitor values

17 replies
Hi guys , had a little bit of time this weekend to check over my M100-2’s speakers, the previous owner did mention that he had recapped the crossover ( and maybe the coils ) now I have a concern as none of the capacitors on the crossover match a schematic that I have , which do I trust ? does anyone have a photo of their crossover please?  
Update! now I’m even more confused as I count 11 capacitors on my crossovers but there are 16 according to the schematic
It looks to me that there are 10 bipolar capacitors on the schematic and "10" on the actual crossover board. I'm assuming that the two capacitors to the right left of the "50" on the board are wired in parallel and should be counted as one. The other caps are (likely) the white boxes, yellow components and the electrolytic on the bottom of the board. Glitch  
Hi Glitch , thanks for the reply. There are 2 soldered together to left of the 50 , thing is none of them match the values of those on the schematic.
The former owner may not have been able to find the exact values and substituted the next closest values.  Piggybacking the capacitors in parallel is one way of getting a value closer to the original. Post a table of the installed values versus the schematic values. This will make it easier for those that want to help to give better advice. Glitch  
I’ll do that thanks
So it would appear that you are correct. is it ok to do so ? they do sound very good , I mean end game speakers. Surely the wrong values will have some effect on their performance?

This is fine. The original caps have values that are not available anymore. Tolerances on these 1970s caps were +/-10% probably so e.g. 47uF instead of 50uF is close enough. Everything the previous owner installed is within spec. Proof of the pudding is in the eating, as you said they sound very good. Close em up and start enjoying!

Done just that , and saved over £100 by not replacing ?   Thanks
