I'm not sure if I tested the tranistors correctly but this is what I did.
X401 ----black lead on middle leg----red lead on base .589, red lead on collector= nothing
X401 -----black lead on middle----red lead on base .589, red lead on collector= 1.2xx
D401 tested good
HOT is brand new
BTW--which are the safety caps and how would I test them?
