I was looking at the attached schematic then read the write up and noticed the schematic shows a plate choke of 100H with 850r. Below is a portion of the write up that says the plate choke should be 15mh with .5r. So 100h down to 15ma and 850r down to .5r. That seems like too big of a difference.
"A choke acts like a passive current source. Of course one could use an active CCS like 317 and co but remember at 3A, there a lot of heat dissipation to handle there and the chips would not less long this way. So I went ahead and use a choke instead. I recommend that the inductance be increase but this is what I have you instead. Values around 50mH would be better. However remember to reduce power loss the resistance should not be too big and should be rated for at least for 4Amps. Resistance of less than 0.5 R must be used. But the value of 15mH works fine too. Preferably the choke should be interleave and section to increase its capability to filter the HF hash emitting from the charging of the large filter cap that is needed to be used."
