Default Re: Question about SS-400ET

* 9-year bump *

I got an SS-400ET which was functioning fine despite its ~2013 initial sale date. All rails were in spec, and no visible cap failures (mostly OST RLS and one Teapo on the secondary). Nevertheless, I decided to recap whatever caps for which I had spares handy.

Primary APFC boost 220uF/400V/85c NCC -> 220uF/450V/105c Yageo (not really necessary - if it survived a decade, it's probably not going to die now. However, I decided to add a margin of overvoltage safety as per Momaka's experiments with his Enermax. The Yageo 450V/1005c is slightly larger in diameter, but the PCB layout has fortunately been designed for this size - bean-counters probably downsized the cap to 400v/85c to save a few cents.).

Primary bootstrap 100uF/25V OST -> 100uF/50 Rubycon YXG

Secondary +5v inboard 2200uF/10V OST -> 1800uF/16V Panasonic FJ
Secondary +5v outboard 1000uF/10V OST -> 1000uF/10V NCC LXZ 8 mm
Secondary +3.3v inboard 2200uF/10V OST -> 1800uF/16V Panasonic FJ
Secondary +3.3v outboard 1000uF/10V OST -> 1000uF/10V NCC LXZ 8mm
Secondary +12v inboard 2200uF/16V OST -> 2200uF/16V NCC KZE
2x secondary +12v outboard 1000uF/16V OST -> 2x 1000uF/16V Panasonic FL 8mm
Secondary -12v 220uF/16V OST -> 220uF/25V NCC KY
+5Vsb 3300uF/16V/10mm Teapo unchanged for now (don't have that value in 10 mm)

Powered up, no bang or smoke and everything seems to be in spec - we'll see if the APFC boost holds up over time.
