I simulated with PSUDII, can't get me simulate open new window:

"a current sink has pulled the voltage below 0 for more than 5 mains cycles, at time 0,100038S"

If I press anyway OK button open other new window:

"the rectifier IFRM (current forward repetitive maximum) of 0,75A has been exceed with a value of 1,25A, at time 2,181013S"

Don't know what AZ1 can do in constant current situation maybe its not taking it well. Ask Rod since its not burning something in the reg.

Merlin calm down, without load tube rectifiers with chokes also shoot higher. How much is normal in your situation I don't know. There you have a full preamp, Rod's design. Here we know nothing but the reg. Reg works back, fortunately no damage. I would make test suggestions but it is not appropriate to start reverse engineering that when Rod is active and helps you. The schematic you posted does not even have voltages on it.

Isn't important because I want to use the reg for ECC81 mu-follower preamp not #26 preamp.

Do something different. Use AZ1 alone, without the extra diodes, see what happens. Use full SS bridge, see what happens.

Default ccs resistor value

Hi,

What is the right resistor value in order to set ccs of my salas HV shunt reg for a current value of about 30 mA ?
I would supply two #26 at 5,5 mA max each. I have two 30 ma choke on HV line in a c-l-c-l-c configuration and would not saturate them . As I also have other two spare similar 30 ma choke, can I put them in parallel in order to increase max current value?

Thanks for your helps!

Anto
