This is a very old thread so probably not being watched?
I discovered one of my machines has the Hong Kong PSU in it when I came to recap and nothing matched.
It is second hand but doesn't ever seem to have been touched.
It has a couple of oddities.
C6 on the low voltage side is a (one hundred) 100uF 200V cap - the same as the 2 on the primary side.
This can't be right and I see yours is actually a 2200uF 16V - makes much more sense.
Also C11 across the -5V rail is in backwards i.e. reverse polarised (+ to -5V and - to 0V). The PSU was running OK and this cap hadn't exploded.
Very odd. Could have beena Friday afternoon job in the HK factory.
