Hi Andrew,Ted a fellow NZ coiler in WgtnGood luck with your MOT design, I've been using MOT's up to 6 MOT's (3 per side) and have great success.
With MOT's in oil I do not think the Terry Filter is needed personally especially with DC designs
I've embraced DC designs with MOT's as the way to go to get more voltage from the inherently low voltages of MOT stacks, the lack of resonance and surging is nice and input power control by selecting break rate is very useful too, (current design needs no variac to ramp it up)
MOT secondaries with a small gap in their EI (0.3mm) make great inductors for DC PSU and the ring up inductor and can be arrayed to any overall size required
Overkill with IN5408's is cheaper and easier than balancing resistors/caps Feel free to call me if in Wgtn Ph 04 938 6638 Rgds/73 Ted L----- Original Message ----- From: "andrew" <andrew@xxxxxxxxxxxxxxxxxxxxx>

HiI have been using Javatc to help me design my coil. I am currently trying todecide on the correct capacitance value for the tank cap but am a little confused about all the different capacitor values mentioned. They are:- Primary Capacitor uF ; I am asuming this is the actual tank cap used.Resonant Cap Size, I think this is the capacitance value that resonates withthe transformer at 50 hz. Power factor cap size, To correct the PF. Static gap LTR cap size, Is this the same as the Tank Cap? srsg LTR cap size. ditto but for a Sync gap. I was planning to use an asynchronous spark gap but from what I have read this is not recommended for coils designed with Java TC,so for simplicity I will go with a multi pipe static gap. My transformer is4x MOT. I am building a Terry filter for it.My question is, what is the best way to use Java TC to estimate the optimumTank Capacitor size. When I know that, I can order my caps for the MMC.
