First thing is the tweeter not working and I know these LE175DLH are built like a tank so I suspected the crossover, when I opened one of them I found the E core inductor coil wet with some kind of oil and the capacitor also seem to be leaking oil as shown on the pic. I would like to replace these components and I started by downloading the schematic of LX10:
1. should I replace everything: C1 (12 uF), L1 (0.9 mH) and R1 (5.1 ohm), R2 (7.5 ohm)???
2. On the drawing first page, I read C1 12 uF but on the second page bill of material I see item 11. Part Number 10434 CAPACITOR .12 uF (is this C1 0.12 uF or 12 uF???)
3. If it is 12 uF which voltage rating should I pick 250, 400 or 800V? can I go little higher as 15 uF, how will this affect?
4. Can I replace the existing ferrite E Core inductor with an Air core coil ( copper foil coil or solid core coil as other options?)
5. Resistors R1 (5.1 ohm), R2 (7.5 ohm), can I pick the 10W?
Thanks and best regards
