Way back in the day, (40-45 years ago) all of us good Catholics and Jews belonged to the JCC to use the outdoor pool.
(WASPs went to the YMCA.)
The pool entry control point was stone countered with roll down doors and some screening near the rafters/roofline.
The receiver that powered two JBL monitors in the control area and all the outdoor bullhorn style speakers was either a Fisher or Marrantz receiver. IIRC, it sat up high on a shelf where it could not get wet. It was however exposed to the KCMO heart of the city heat/humidity plus any extra that comes off off a 25 x 50 meter pool with a connected diving area
I distinctly recall a mid sized tabletop oscillating fan that ALWAYS cooled the receiver. Sometimes a box fan was cooling the counter workers but the fan described above had but one purpose. I know that receiver put in multiple seasons.
I would buy whatever the cheapest receiver I could get that works with what I have and drive on, keeping it as cool and dry as possible. If I got 3-5 seasons out of the receiver, I would be happy. 5+ would be gravy.
FWIW/YMMV Greatly
