Clay Boss wheel - blown circuitboard - I need a part, but from where? =?iso-8859-1?B?dPZmZg==?= 04-09-2007

Didn't just blow the fuse, also blew the yellow disk capacitor on the
circuit board (and I hope nothing else!). The board is marked KBDM
REV.A 111894. It's Creative Industries Clay Boss, nice little wheel if
I can fix it.

Problem is, the capacitor has no legible value on it, like in farads,
so I dunno how to buy a replacement part. All it says is "Z151 09UL"
and I can't find a meaning for that.

So, question: anybody know the capacitor value, or have an actual
schematic for the board?

Alternate question: is there any place I can just buy a replacement
board for less than the cost of a whole new wheel? Anybody got a Clay
Boss with a broken motor, willing to part with the circuit board?

I'm beggin' ya, here! Thanks in advance,

ITYF it's one of these: http://tinyurl.com/2vr6xz

iACVolts=3D150&iDCVolts=3D0&iDiskSize=3D0&stylenum=3DD6921ZOV151RA09

Any MOV of similar rating will do the job.

Do you know what made it blow in the first place?

Wow! You found it! .... 760 pF, I know what that means, yeh.

Bit of a mystery. The working theory is that the power line we plugged
into was 240V instead of 120V. it sure looked like a 120V plug to me!
But that's just a theory ... the outlet in question is way across town
and it's kinda moot to go back and test it somehow.

Thanks for the link, that's fantastic! :D ... Off to Radio Shack ...

You do realise it's a MOV (metal oxide varistor, a surge protection=20
device) not a regular capacitor?

Hmm, no I didn't, until I read the spec sheet.

btw, don't bother with Radio Shack for anything like that. They're all
cell phones and car stereos now. The guy showed me where they hide
their three little drawers of (and I quote) "capaci-tators" :-D

So I'm off to a real electroniocs store tomorrow.

Thanks again for the help! With luck I can reinvent the wheel ... I
mean, repair.
