Learned a lesson today. Used cheap radio shack batteries in my PH3D when I bought it a few months ago. I thought it was funny that the light seemed to dim rather soon with them, but it still worked. I thought the sound could be a bit “off” in the dynamic department, so I thought I’d try fresh batteries today.(Duracell).
It turned out one of the old batteries had leaked pretty badly, destroying the paint and even pitting the steel… Wow. I guess the next time it starts going dim early, I should suspect a bad apple in the bunch and get em out. Thankfully the design places the batteries well away from the main board! Yikes!
Anyway, take care and have a great summer.
