Resistance isn't futile it's V / I.

Thanks - another 8 would be handy for two more boards. Will you be at Owston ?

I bought 3 syringes of thermal grease ... no idea why, I can't see me getting through 1.

I'll bring the other 2 to Owston, anyone who can use them is welcome. Actually I wonder what other surplus I can dump on somebody, I mean I wonder who else might benefit from my treasure trove of goodies ...

Experimenting with something separate, my caps were all at my brothers so I used one of the 5600uF caps supplied with the DC boards. So THAT's what a blown capacitor looks (and smells) like.

No harm done and all valuable lessons. Andrew could you give me a link to the ones supplied please so I can check the datasheet and see where I went wrong ? I take it any 105degC 16v 5600uF cap will be fine ? I'll get some spares too.

This one ok ?

Hi Mick,

I wont' ask what happened. You really need Panasonic FR Series, high ripple, not cheap but worth it.

cheers,
