Need help again for power supply

49.130.130.15

Hi again!
Whether power supply with following tubes able to handle 5 x ECC83 (2 for phono and 3 for line section)

6Z4 (rectifier)
6J1 and 6V6 (regulator)

Thank you 😊

This low current draw would be a perfect place to use a couple gas regulators in series. Much simpler and they provide a nice glow, too.

  Those gas tubes can be somewhat noisy. Also, there is a limit to the amount of current they can shunt. You will need to shunt an amount of current equal to the total amount of bias current your of your 5 tubes. Being as how they are ECC83s you should be OK. This would be a good place for your cascade MOSFET CCS. Instead of a resistor feeding the gas shunt tubes use the CCS. Much higher AC impedance. Just set the CCS to double the bias draw of your 5 ECC83s. Try to have a least 30V across the CCS.

12ax7 does not (can not) draw a lot of current. Maybe 2ma. per triode near the high side.
The 6x4 is rated at 60ma. It should work just fine.

  Thanks for your help again!!
  
  I guess the 6V6 should be no problem to handle 5 x ECC83, right?
  
  One thing forgot to mention, the resistors for cathode follower of both phono and line section has CCS there, so I expected more current is drawing from the supply from the supply.

    The 6v6 will be fine and no, using or having a CCS doesn't mean more current flows.
    I'm with TK. For a low current application, VR tube shunt regulation is the way to go. It is much more simple.

      I'm only use CCS for plate load and cathode follower
