Reply to "TIU and power supply problem"

So when you connect your postwar transformer to fixed in 2 on the tiu, with nothing connected to the fixed 2 out, your meter reads 0 volts on both input and output of tiu fixed 2?

What does meter show for continuity/Ohms between red and black Fixed In 2 jacks?  Does it indicate a short circuit?  If so perhaps your TVS protection diode inside the TIU failed (is shorted).

In which case, not sure why the Powerhouse did not protect itself and is now dead...but if your PW transformer reads normal voltage by itself but 0 Volts when attached to Fixed In 2...then it seems to me TIU Fixed 2 is internally shorted.

This seems like the case... but if the TVS is a dead short, then I’d think the breaker/fuse in the postwar transformer would have popped, and or a shower of sparks and some magic smoke.
