Hey,
I picked up (2) pairs of HPM 100's...now before you say not another freggin HPM thread please finish reading because I have searched on our site and can't find the answers I am looking for.
Looking over the SWN-117 & SWN-158 schematics and to me it makes sense to replace the electrolytic capacitor but I can't locate an audio grade 0.15uf/63v bipolar electrolytic lead type capacitor. Has anyone found an acceptable capacitor? My go-to is mouser for audio grade capacitors but they never seem to have audio grade bipolar type.
Is it recommend that I change out the 3uf/100 & 4.4uf/100 mylar film capacitors? If so, what is recommended? I saw one guy use (2) capacitors in parallel to achieve the rating of what was removed. However from what I have read MF types shouldn't go bad.
Also, I watched a couple youtube videos on restoring crossovers and those people were upsizing the resistors, the coils....why?
Thanks, James
