SL-D303 Recap?

[J1mbo]

TL;DR - complete recap? Or be selective?

--

I've recently acquired a D303, which after a clean and lube is working well. The main reservoir cap is an unusual size, but I've got an over-specified part on the way from mouser.

I've read some suggestions to leave the rest of the caps alone. However, this eBay recap kit is suggesting the opposite, that leaving old dry caps in the servo circuit could actually damage the servo IC (AN6636). There aren't many electrolytics in it, so replacement is easy enough.

Thoughts? Pull the rest and replace with Panasonic EB?

Technics products of that era suffer from leaking Matsushita caps, so I'd replace them all. Leaking caps left alone for too long will eventually damage the circuit board, requiring much more extensive repair efforts than just simple replacement. Replacements are largely a matter of personal preference. Just use bi-polars where they were originally bi-polar, low leakage for low-leakage, etc. If you like Panasonic, I'd go with FC/FM/FR for general purpose caps, and SU for the bi-polars. If you need low-leakage, Nichicon UKL when they can still be found, or Rubycon TWL.

@nakmandan - thanks. You were right, one is indeed leaking. And it's one that isn't in either of the service manuals I can find online, so good thing to have checked them as a recap kit wouldn't have included that one anyway.
