This came up in another thread and we thought we should start a new one. AK member Nat posted this:
"I may also start a thread on this since there is a 303ax crossover question somewhere else, but the values of the caps in mine are: Low pass: 16mfd 50V in parallel with the woofer, I assume to produce 12 db/octave slope, and unmarked value transformer used as the coil in series with woofer and cap. High Pass: resistor (green/blue/yellow or white/silver color code, but forgot to check value, and uncertain about colors) then two switched caps, a 6 mfd and a 16mfd, both I think 50V and then to the tweeter and to a paralleled ferrite core coil, again unmarked and again I assume to produce 12 db/octave slope. Mine had wax over stuff so not too hard to move the caps to see values, but colored the resistor.
It occurs to me that the resistor might be in parallel with the tweeter, but it was hard to tell because the switches were made air tight by covering up with masking tape and wax.
Hope this is helpful."
I know a lot of us have these speakers and have failed to recap them because of the black tar stuff that holds the caps in place and makes it difficult to see the values. I plan to leave the old caps in place but wire new ones in their place.
Thanks Nat!!
Take care,
Ed
