@herd yes it does look hot and thought perhaps you're right, but checked and fan all working well (now anyway )

Took the board out I see that must be CP4

Just to close this off, PSU re-capped and put a trace in from 1-4, all good for more Lemmings!

Hi @techknight is that CP15? and can an 'ordinary' electrolytic aluminium type capacitor be used - looks like some special kind of capacitor? cheers!

Oh boy, odd size, thanks @Phipli. Maybe a metric to Imperial conversion🤷‍♂️

Thanks Scott, looking for the thread size, T15 is the torx head size. I’m replacing lost bolts you see. I’ve seen M3 mentioned but not confirmed

Hi all, does anyone know the thread size for Mac classic case bolts? Thanks!

No wiring diagram I’m afraid, if you have the original battery you have as much info as me

Thanks both. I think I've found the answer. Looking for images of the board I watched BigBadBiologist's recap video on Youtube and got a couple of reasonable views. Outlined the same area for clarity. Doesn't look like 2 is joined to the 1-4 trace.

Can’t find a schematic for the psu, Im wondering where the solder mask and trace has blown away would the trace have joined up or has the leaked goo caused a connection that blew away the mask? In the annotated image 1 is the negative leg of a capacitor, 2 &3 are resistors. There’s no...

yes that makes more sense, thanks 👍

Ok right, C13 is aluminium electrolytic do they pop?

Hi all, just settling in for a Lemmings session on my old faithful Q650 and a loud pop followed by the mains tripping occurred. Looking inside the PSU it seems like it could be the capacitor at C13, the board is quite greasy looking here and there. On the back you can se the trace has been...

Hi @maceffects +1 for a SE board if you can keep me in mind, although where are you re. shipping? I'm UK. Cheers!

@olePigeon good shout I'll get some switch cleaner in there (never seen Dioxit in the UK). Thanks! @croissantking really useful. I'll have to sooner or later but sooo many caps! 😥

Oh yes for sure it has other problems, but this is much better. Need to track down a line output transformer.

Afraid not, only a small Amount of adjustment available, perhaps could change for a different value ?

Ah brilliant thank you, there was a little bit of anti-clockwise movement. Made it much more useable 🙌

Is it this one at the top? seems to adjust focus but got it as good as it can. I've not taken it apart yet
