Relative newbie here.
I'm rehabbing a Sony TA-F444ES II, replacing the fusible resistors and electrolytic caps. The PS filter caps are Nichicon Great Supply, 12000uF, 63V, squat in form factor: 2" (about 51mm) L x 2.5" (about 63mm) diameter. They were mounted to the board with beefy solder tabs spaced at 16mm c-c. Getting them off was not easy, but I digress.
So far I have not found a replacement cap with fits well in the case and has solder tabs with the correct spacing. The closest I've found is the Nichicon KZ series, LKG1J153MKNF in particular - 40mm diameter x 68mm long/tall, which might be too tall for the case. At least the padding on the underside of the top surface of the case would need removal.
The KEMET ALT22 series are close, but have tab spacing of 10mm, which is probably too narrow.
Both the Nichicon KG and the specific KEMET ALT22 seem unobtainable - None of the big houses have them, the regional reps ignore my calls, and KEMET HQ ignore me as well.
The current plan is to solder copper tabs onto the snap-in pins of Nichicon replacements, then additionally mount / support the caps with (nylon) standoffs glued to the cap case and passing through the existing cap vent holes in the board. The caps I've chosen (still 12000uF) are physically much smaller.
I realize this question comes up a lot, but I have not yet found a better answer. Thoughts? Thanks. Tim
