Tubes?

no, i am nuts, sure the electrons can walk in..
but they cannot walk out because they are blocked by the other diode,no closed loop 
Steven also sais he took a 500-0-500V 300mV plate transformer which i think should be 300mA.
and he measured the output from the tube as 500 volts DC at 250mV where i think this should be 250mA.
Any way let's not argue about this and continue...shall we.

marco i just found that osc and a long discreption i will post the schem and this is right out of 1 of the old books im sure i have more info on this osc but this is the first i have found 

comming right up

I don't think we're arguing Marco.

If you would prefer to drop the discussion, ok. I guess we're looking at things from different perspectives, but in the end, our perspective does not matter...because:

The circuit works...the filament is heated, it bleeds electrons, plate current flows, we get full wave rectification, and finally a B+ when filtered.

In the process, the plate and filament transformer currents interact, and that is all SM was trying to point out. Nothing more.

yes ,the electrons which are boiled off the cathode meet the electrons from the plates.
So the 5VAC meets the 500VDC.
but i constantly monitored the ac voltage of the heater and it did not show any sign of the 500VDC with it,which i think is normal however the 5VAC does combine with the 500VDC and i think we have a nasty situation here.
