The fan in my Palomar 500 elete calls for Sunon model no. fan 1209ptb-3 12v 1.6w. There are many available on eBay but I can't find that exact model number. I would like to replace it with a sunon but if there's another brand with the exact spec's I listed and if not can someone post a link to a fan that will be a good replacement.. I don't know how far I can stray from those spec's. My knowledge is limited to zip.I'm not concerned with the price or brand. I just don't want to replace it with something that could damage the fan or worse the amp because I deveated from the voltage and wattage. I don't know how much I can deviate from the original specs and have the fan work properly without drawing too much power from the amp itself, and possibly ruining it or not keeping the amp cool enough. Thanks for your help. You guys are excellent.
