I know this is a dangerous practice, but obtaining a transformer to make a vacuum tube power supply in my country is prohibitively expensive. So i have to go for transformer less psu. I am just making a very simple TUBE tester to check if the grid voltage is really controlling the plate current. Now this requires both + and - power supply. I should be able to completely cutoff plate current by making grid negative. I am presenting my design of power supply. Have anybody designed something similar? Correct me if some flaw in my design.
Your bridges have the diodes swapped compared to the +/- markings.
The bridges short out the capacitively coupled voltage. Try it with four 2uF capacitors rather than a single 1uF.
