Thanks Derek. Yes I’ve changed C201, C202, C203 (and the C3xx) plus C23, C20, C99, C27 and recently C18 in the can though not tested it since the last change. C18 was reading about 17uF so working but well out of range. I’ve tested C15 but not changed it.
Wondering if I should change the transistors- will stress them with cooling spray first if I can
