Vintage gear

found in a wooden pole box was this absolute pristine example of a BLI leak transformer rated for the first gen SOX, SO/H and SOI lamps. It dates to between 1964 and 1967. here used to be aP42 2-part cell before the SS55 was fitted, but there is no capacitor. I could guess that the capacitor was in place of the P42 cell if there used to be a 5th core feed for the unit, or it was in place of the cut-out if there were ceramic fuses previously. Still, this is in stunning condition for its age!
