Ok. How to set up mfsu's to a reactor without set up a transformer, well you take like 4 mfsu's hook it up to a 4x hv cable. and then hook the cable to the reactor. IN THAT ORDER. don't put the wire and try to set up the mfsu's. they will just go KABOOM. if ya want help I can help. I'm really good wit tekkit. still learning lite tho XD
By the way. I have 1 set up on my world. it has like 14-18 quad uranium cells and it don't go above 1 heat. I have it cooled perfectly. I could probably get more if I tinkered with it. but My point is I have all that going on and I am using straight mfsu's (a lot better power output then hv transformer. if you would like a picture of it. I will send it. thanks. Have a nice day. hope this helped
