Experts disagree...
I thinkn V1 might be a voltage controlled current source. V2 seems to screen driven with external-insic feedback. |

As of this drawing, neither Anti-Triode nor Spud. Shoot me!
The 6DJ8 StackOdified MuFollower at the left shouldn't prove much of a head scratcher. Driving 10K into the output stage's Screen Driven A2 External-insic 4th Circuit Emulator network is where my noodle really seems to get wrapped around a fork. I am far from certain the values specified on the right side are anywhere near optimal. The part count at first glance does seem kinda high: But on the other hand, only one component is a cap. PSRR is probably as good as the constant current sinks. And bias in both stages is auto-set by sunk current. B+ design will be dirt simple. A few of the parts I drew could easily be omitted: 24K that limits screen current in event of an arc... 1M just in-case the pot at the input has gritty spots... 50R degenerative feedback below the Stackode... A whole mess of lossy ferrite beads... Q: Is Stackode equivalent to a Triode Strapped Cascode? |
