[sdiy] Power One HAA15-0.8-A PSU

[tom wisdom]

hi all,

just a simple question: do any of you have the HAA15-0.8-A model, and if 
so, could you tell me the value of resistor R22? i was testing one of 
those old paia modules last week, and it fried this resistor bad enough 
to obscure the color bands on it. i wrote to the people i bought it from 
to see if they could tell me the value, but haven't gotten a reply.

it's a bipolar supply, and the board is laid out semi-symmetrically, so 
it looks like it might be the same as R28, which is 
brown-brown-green-violet-yellow. which brings in another question: what 
is to be done when there's 5 bands instead of 4? i read on a website 
that the third band is another digit, the fourth the multiplier, but 
this seems to result in undefined values (since violet has no value as a 
multiplier).

regards,
tom
