I found a busted bp6 at a junk sale.. from the looks of the board i need ot replace Cap's ec18 to ec25 (inclusive)
and L17 and L18
BUT these parts are damaged and i cant see what they are supposed to be can anyone lend a hand a tell me the specs of the CAPs and the items on L17 and L18
cheers

Replacment Cap's
My BP6 is done now, a few changes, all of the 1000 and 1500uF capacitors have been replaced with 4,700uF 10v capacitors also EC10.
The 100uF capacitors have all been replaced with new 100uF and the one 10uF has been replaced by a tantalum capacitor.
While I was at it I have altered the ventilation on the power supply and put arctic silver on the greenie....
Results better than I had hoped, dead stable and running 560Mhz on air cooling, unfortuately CPUs are 466 so pci goes too far out of spec at any higher clock. Will post pics on my webspace and update on here if I do anything else...

I did not know for sure it would work.... though electrolytics are wide tolerance components at best..... I would go for slightly smaller capacitors next time purely because the diameter of these capacitors made things a bit cramped..... the BP6 is ok running linux at 588Mhz but less in Windows XP pro.... realistically it is solid 24/7 at 525Mhz (75Mhz fsb on dual 466s)....... the capacitance is probably secondary to the esr of the capacitors ( effective series resistance ) .. no trick cooling any more!
Sorry, I forgot to mention.. the Maplin caps are quite a lot bigger than the originals, I made a mistake with guessing the diameter! Also I have crappy OEM type heatsinks and fans these days so I was not worried about tall capacitors around the CPU sockets. I have a tatty web page http://www.g0fvt-hamradio.dsl.pipex.com/ I am sorry it is so bad, I hope to do something better when I find the time!
