Hi John,
I'm an EE and an audio enthusiast of over 50 years, for what it's worth. I highly recommend that you not change any resistors or inductors unless you know that they are out of specification. Wirewound resistors also have a certain amount of inductance as well, so I'd recommend NOT changing resistor types or values unless you cannot find suitable replacements that are equivalent in value.
Last year I replaced all the electrolytic capacitors with high quality film caps. The large value ones were also big physically so I had to get creative in mounting them, and needed to mount them off the board, right next to it. I used 18 gauge wire to connect to the crossover, and it worked out well.
I found no resistors on my crossovers that were out of tolerance, so they remain stock as did the inductors.
The film capacitors made a nice improvement in clarity and staging. The speakers sound great. The previous owner took good care of them and when I bought them 7 years or so ago I refoamed the woofers, bought a Dahlquist LP-1 active crossover, and got a pair of Dahlquist DQ-1W subs that I used instead of the stock stands for the speakers. They're driven by a pair of rebuilt Phase Linear 700b amps, upgraded with White Oak driver boards and ON semiconductor outputs. Also I used a DC protection relay in each amp for safety's sake. I don't want my woofers to become wallpaper if an output transistor goes face down on me.
While I'm thinking about it, I want to thank the board moderator for going throught the effort and time to transfer this group to it's new home. It's way better than Yahoo groups was. THANK YOU!!!
