Re: help wanted with RPM gage
I have pictures of some tach internals, though I don't think they are from a 69. In any event the only transistor in the thing is a UJT and it's in a plastic case. I've seen a lot of transistors in my day and the only ceramic parts were high frequency RF types.
Can you post a picture? I have pictures of the tach guts, but no place to host them (so I can't post them).
