I'd suggest picking something from Orion, supplied by Arrow (free shipping,
too). Use the 80-120? VAC selections, maybe a little more power than what
yours does or you've seen posted... the higher-speed ones will be
noisier... measure your width of fan or spacing between boltholes, and
thickness if it's important, to select one that fits well. If you have a
choice, pick something under 3000 rpm (less noise).;Shape:Square;Category:AC%20Fan;Manufacturer_name:ORION%20FANS;In+Stock:Yes;&sortBy=Operating%20Input%20Voltage%20Range%20-%20(V)&sortDirection=asc&perPage=50

Different amp, but we've used this brand for a supplemental fan for an
Alpha 87A and are very happy with it.

You'll pay something like $15, delivered.
