I have a TA-200 that seems to be letting water inside it from the top. I had a channel stick on the other day in the rain and it happened again yesterday in the rain. When i opened it up this morning i have pools of water seating on top on my heatsink and some seating in the bottom of the box too. The TA-200 lookis fine i don't seem any cracks or anything else and the box is mounted straight up and down like it should be. I have 15 others mounted the same way and now of them are taking on water???? Any ideas what or how the water would be getting in the SSR???
