I'm planning on building a transformer box, so I came up with this bias circuit. I'm a complete novice at circuit design but I would be grateful if anyone could critique it or rip it to shreds.
V1 is supposed to be the 60hz output of a power transformer (I arbitrarily chose 700Vpp, but I tried it with 940Vpp and it seems to work too), and the zener string is 2x 200V and 1x 180V. Blue line is the sine source, red line the node right before the ballast resistor. The runtime of the simulation is 0.4 seconds. I know it's probably a waste of money to use a power transformer for a bias supply, but are there any issues with the idea other than cost?
