Im just wondering how warm do most MMC banks become. Im looking for some
personal experience answers here. I ask because my cap gets warm after a
bit of running. I would say that my cap heats up to about 102 degrees(F).
Off hand i do not know how many degrees C that is. My GE caps are rated to
85 C. I have a feeling that they are not that hot. Im running my TC with a
reconditioned NST(12/40). My cap consists of one string of 8, GE .068uf for
a cap of .0079uf -at- 24kvdc. I would have to say that my transformer primary
gets warmer than the cap, just to give you all an idea of the temperature.
I can hold my hand on the cap with absolutely no discomfort. I hope that im
giving a good description of how warm they get.
SOOOO... is this acceptable, or am i going to ruin these caps soon?? Ive
tried my next best cap configuration, 2 strings of 10 caps for a .0136 cap,
but this was much too big, and gave weak performance.
Also, I was wondering what my perfomance would be considered(good or bad).
Heres my specs:
12000v ~40ma NST
9 gap static RQ type set at a tad bit over 12000v
.0097 GE MMC
Twin coil set up: pri, 3.5"inner/12"outer diameter, taped at 5 turns
Secondaries are 2.5"x 10" wound with 28g, 2"x12" toroids.
My best spark so far is 26" with a breakout point, and 22" without a
breakout point. Unfortunately, i could not get my SRSG to work.
I would like to hear what you all think about my MMC getting warm like it
does, because i really would like it to last a while.
