Several years ago, a friend of mine built a small sound unit that produced the sound of an operating mechanical reefer. It was small enough to fit inside the car. The circuit diagram apparently came either from MR or RMC, probably late 70s or early 80s. He is trying to find a copy of the plans. Can anyone out there help?

a little help (maybe)
It WAS a great help! Now, how do I find a copy of the December, 1988 RMC?

Right here............
Jeff:
I have the RMC issue. The unit is powered by a 9v batt. Is that the one ?

I don't believe he said anything about battery size, but that seems to be the article he's looking for.
