I am restoring a pair of Rectilinear model X 3 way. The crossovers are giving me heartburn. The resistor for the tweet ( which I would like to replace) is a color coded 6 band and is coming back as 42.9 M ohms according to all on line calculators. 0.043 ohms, makes no sense because it seems like too small of a value? Also there are two pots (Lpads?),the smaller one is marked 14 ohms for the tweet and the other is a larger variety marked MG 15 for the mid. I would like to replace both but I can't find an exact match. Would a 16 ohm L pad from Parts Express work for the tweet. I don't know how to determine the value of the mid pot.
