I may have screwed up.
I was looking thru the schematics here "https://forum.polkaudio.com/discussion/55888/polk-audio-speaker-wiring-schematics-amp-more-stereo-dimensional-array-sda#latest" in an attempt to find the correct one for the SDA 2B "TL" MOD for 198 tweeters. There is none listed. When I looked before I think I got confused, easy for me to do with the meds I take and looked at the one for Pin/Blade instead of Blade/Blade and Blade/Blade are the ones I have. One piece circuit board marked 1987. So, does this mean no RD 0198 upgrade ? I sure hope not as I have the capacitors ( 5.8uF Sonicaps) and the RD 0198's ordered. Thanks.
Where in Alabama ?
