[QUOTE="Ampdog, post: 44268, member: 144"] Similarly apology for chipping in: I did not see the power supply circuit and am commenting basically. Yes, a power supply choke MUST be gapped. I tried ungapped (with C-core) and it was a miserable mess. For ungapped one needs a HUGE component. Then, active current source also under investigation (chokes are expensive). That can double as a controlled voltage rise-time device, but there one can be stuck with some serious heat generation, depending. (Chokes are reactive thus no resistive heat generated.) If chokes are of further interest, I suggest we generate a separate thread. [/QUOTE]
