I greatly appreciate all the good advise here. I recently received an email from someone who had an extra crossover they were parting out (from TC-50) and they volunteered to send the inductor coils that they did not require for their project. I will use these in the repair of my crossover that is missing this element. I appreciate jeallen letting me know about the fact that the coils were not where these were changed for factory specs. BTW, I found your site very helpful in this project. Also, while all the caps visually appear to be in nice condition on both of my crossovers, should they be replaced due to age regardless? If so, I was advised to use same value electrolitic ones? Is this the common wisdom on the matter? Thanks again for everyones help.
Spica TC-50 crossover repair
Recently got a pair of Spica TC-50 speakers in a trade. Nice looking speaker that from all accounts is a nice sounding set as well. Original boxes and original stands. Problem is one of the speakers has a crossover that was in the process of being repaired and is missing the three coils. My question is: is this worth the time and effort to repair or should I give up the dream? I have a schematic that lists the parts required, but the web site I got this information has a caveat that reads "Spica carefully graded and tested each woofer. Then based on those parameters a service code was assigned and paired with a matching crossover. For this reason, it is unlikely that your components will match these exactly" I assume if I were to replace the coils in one crossover, they should also be replaced in the other (complete) crossover. However, this statement leads me to believe it may never be completely "right". Or will difference likely be negligible? Lastly, are any electrical DIYers out there that can tell me any relatively easy ways to test the woofers as Spica did in order to select the proper coils to rehab these speakers. What is the opinion out there? Thanks, Whyland
