Mains side the main smoothing cap is a 400V 33uF

The one thats gone fishy is a 10V 1000uF cap.

Here's the other side ( DC low )..

I'm not a fan of the chineseium caps they use in those.

Done that on someone elses and was a nice easy mod, but wanting to get this working so can pass on the whole thing..

All ordered, had to order 2200uF 50v instead of 40v, but should be fine..

the princely sum of £11.00 from Farnell ....

Could be another Amiga Power supply rising from the dead !

I must have been lucky cause mine had Nichicon inside, unless they were fakes :)

They arrived and installed them this morning, it's alive ( and no fishy smell )..

And the Amiga that I got with it, ( seals intact ) seems to work, but I don't have the wire for the 520 😔 so unsure about video, but the lights work and the drive does the appropriate clicky seeking type noise... Very Happy

For a test could you not use the mono composite video out instead?
Just remembered the A520 does colour composite out too, might be a option with modern TVs, I guess RF is no more :(
Hated them A520 modulators they always seemed to blow up on me :lol:

TaDaaaa Very happy, it's alive :)

Now to try and source WB disks etc..

Now that's awesome, looks shockingly clear too :D
My A500+ mono out looked like crap, whoever's idea that was adding that well.... :lol:
