    HELP - from our electronics gurus

    The symbol indicates a diode, Pete. If you were to solder in a bridge, you will likely have some kind of a problem. The manufacturer wouldn't install a diode if it weren't needed. Hopefully @MtnMan or someone else wiser than I can tell you more about the type of diode based on the colored...

    Wanted Whelen Edge 1985 Power Supply

    SMD (surface mount) components are so tiny they're generally picked and placed by robots. This technology was only in its infancy in the 1980s. The capacitors used in OP's power supply are through-hole mounted.

    Wanted Whelen Edge 1985 Power Supply

    I don't think any of those variants existed until well after 1985. His is one of the earliest Edge bars. Notice the full-height lens optics and the j-tube corner strobes.
