You probably do NOT need to replace the big 150uF/450V capacitor. It's
not the high voltage low ripple current capacitors that fail. It's the
low voltage, but high ripple current filter caps that get hot and blow
up.

Tolerable. It's not a low ESR type, but it's low enough to work.

It's low-ESR (although the data sheet doesn't clearly show this) so it
will work.

Also low-ESR and good quality cap. No problems.

Looks generally ok.

I'll leave it to you to determine if the case sizes and lead spacing
are the same as the originals. Neither is particularly critical as
there is usually plenty of room. One suggestion is to use the next
higher voltage rating capacitor. The 50v cap will probably remain
50v, but the 25v caps should be replaced with 35v caps. They last
longer, have a lower ESR, and aren't that much larger.
