I came across this schematic and was considering the build, but the more I stared at the power supply the more confused I became. Does it not appear as if the diodes in the low voltage section are drawn in reversed? Or am I just not understanding something?

Comments anyone,

Thanks,

Phil

The rectifiers on the heater section are reversed.

They are wrong. Aaaand there is one capacitor on the heater supply bridge wired wrong as well. It is the 3rd one down in the sch wrongly connected to the cathode of the bridge. It should go to the anode in parallel with it's diode. Easy mistake to make given the person who drew it was standing on his/her head looking into a mirror though. Made it myself I admit. Once.
