3) There is a mistake in Milq circuit. The B+ of the driver stage has almost insufficient amount of critical inductance. It was because I drew the circuit having the Super Milq in my head where the PS was feeding 3 stages and consequently drew more current. I recently opened my full range Mils and confirmed that I have not 15H coke in there but 30H. So, ether you increase the current you draw across the PS lowering the R23 bleeder or increase the value of the L1 choke (Hammond has 30H and 40H chokes that do very nice). My presumption is that any PS with input choke should be tested in continuity, so it is easy to see what is going on…. 4) It is not necessary to run input choke filtration for the Milq’s bias supplies. If you wish to do for CRC filter before the gas tubes then it is fine (use input cap of a small value thought). You will also need much lover voltage on the secondary of the bias supply transformer. With input choke the bias need to be 220V as the input choke will eat up ~10% and the gas tubes need 190V to light up. With input cap you will have an increase voltage from bridge and I would go for 140V-150V on secondly if you use CRC… 12) Put two 10R, 5W resistors (in each leg) between the rectification bridges and secondary of the power transformers.
