Hi Don,
Yeah that is an old production KLM-366 / 396. I may have one bad voice chip on it, but in general it's pretty good.
On the KLM-370, the acid somehow went through the earth wire, and destroyed about 20 traces on that board. It took around 3 hours to clean that one up, but it was relatively easy given it is a single sided board with minimal components. Something I was not expecting.
The original KLM-367 board had less battery damage to it, but because a clone board came up on ebay, I just grabbed it.
Oh, and my TL5514 RAM chip is shot as well. Easy one to fix.
Anthony.
