Greetings again, my devoted flock.....(I'm sure glad you are still there!!!). In this shot, the back panel has been removed to show you the 9-volt battery on the left which powers the unit. The tweeter is seen on the right with the input connections below it. A transistorized circuit board is seen at the bottom of the enclosure. This I removed from a telephone listening device which does the same job here.
Well, that's all folks!! Thank you for your undivided attention and watch this space.....My repertoire is endless!!!!
