Started the power supply.
First thing I did was build the tube rectified circuit on the breadboard. We ended up with about 190 volts on the B+.
Now we know the transformer is 250 volts but this is what happens when you use tube rectification.

I then built up a solid state circuit. But this time we get 390 volts on the B+ and a tap for the preamp at 190 volts.
Remember this is unloaded. No load on the supply.
