5R4 and 5U4 solid state replacement on an Apache or Marauder

[Peter A Markavage]

My Apache has been running homebrew solid-state rectifiers in the low and
high voltage supplies since the early 70's. I built this Apache in 1959.
It still has all the original transformers. None of my active boatanchors
have tube rectifiers in them any more.
