Hey guys! After having recapped and otherwise modified a couple of old amplifiers, I never thought replacing those three lousy caps in my HPM would be where I need to actively seek help here for the first time. I do wanna thank everybody for all the passive assistance this forum has provided to me in the past, without which I had not been able to bring some of my gear back to life!
I have a pair of HPM-70s. These are actually closer to the 100s than they are to the 60s, in specs and build. Three caps and a resistor, in my case 0.3, 3.0 and 6.0uF, and 8Ohms. This translates to 2000, 3000, 12000Hz crossover frequencies.
Now, I could reproduce these values using a number of smaller ones, but I wonder how much it would really hurt to deviate from the original capacitances a little bit. For example with a 6.8 and a 2.8. Might this even bring down the low crossover and raise the mid one? That would be fine with me, obviously. I'm just not sure what other effects a 13% deviation may bring about. Having followed the discussion in this great thread I get the impression that in crossovers these differences are somewhat more critical than in amplifiers.
Please tell me your thoughts!
