67 is flakey

[mbielman]

Hello!

I pulled out my 67's last week and one of them didn't work. Not dead, just acting a bit crazy. (Here we go again) I was troubleshooting w/my scope and after about an hour, it was working! After a while, I put it back together and a bit later, same failure again. After working on it yet again, I discovered that if I leave it on for an hour or more, it works. Let it sit (OFF) for a short time and it's bad again. This is very repeatable. Thinking it might be temp related, I heated it up but still bad.

I think I cleaned this one up from a leaking battery but not sure. I had to do that on more than one, if memory serves. Someone mentioned that if I had to do that, there might be battery junk under the ICs. What do you think about that? (I have a desoldering station now so I can pull chips if I have to)

Thanks!
