Vintage 24V Power Supply (Wolfe & Reed)

This is an old, linear power supply, probably from the 1980's or earlier. It's still in the original box and has probably never been used. Equivalent modern power supplies weigh 1/10 of this and a much more efficient, producing much less heat, so this has no real practical use, aside from historical or educational use, meaning the circuitry is probably easy to understand and repair.
