It appears from the 5 or 6 pairs of Monior 10 crossovers I have looked at(serial between 70,000 and 123,000) they all have the same cap values and same resistor values (2.7 and 2.5) This incudes early 10s (Denmark Peerless) 10As (US made Peerless) and early 10Bs (SL1000) The only difference is they started switching to electrlytics in 83. I have a pair of early 10B crossovers one is one type of cap the other has electos.
Here is my question Below is a picture of a 10A crossover (which i believe my early 10 looked like) and one of mine from my early 10s. About 17 years ago i was talking to ken (the man) at Polk and he said just send me your crossovers. He redid them The one with the big yellow caps are the ones he redid. The values are the same but he used a different type of cap in one postion and the resistor is a very long 2.7 and then a 2.0 not a 2.5 What did he really do here?? I would like to understand 1) The one cap change 2) the long 2.7 and 2.0 verse the short 2.7 and 2.5 on the priginal Thanks,keith
