Thanks again for your suggestion to replace the capacitors in the crossover, but I,do have a couple questions. My electronics knowledge needs some assistance, but I have searched the archives until I am blue in the face.
The original capacitors in the crossover are polarized, axial, electrolytics according to the schematic and pictures. Is it okay to replace this type with a metallized polypropylene capacitor of the same value that is not polarized?
Is your preference for the Dayton metallized poly caps because they may not change the high frequency presentation?
I do not plan to change the coils, but I thought the grille change may be a good idea. That crosspiece in the middle of the original grille may interfere with the tweeter, as may the grille fabric.

- I'd try out adding a small amount of R in parallel with the new capacitor as its equivalent series resistance - Timbo in Oz 16:18:42 02/05/17 (3)
- Your post is over my head. Here is the crossover schematic. - alaskahiatt 19:48:45 02/05/17 (2)
- okay, you seem to have a 4-position switchable level control on the treble. - Timbo in Oz 20:25:52 02/05/17 (1)
- Thanks for the response. Yes, they are wirewound resistors. nt - alaskahiatt 21:30:56 02/05/17 (0)
