Title: k7400 problems
Post by: fargen on September 12, 2006, 09:19:22 pm

heya, i have two of these chassis with the same problem and it is driving me nuts. The b+ is running around 40 volts and I cant seem to understand why...check the diodes, seem okay...changed the uc3842, changed the pot no help on either...seems to be over in the left back area. I just cant seem to isolate this...anyone had this before? thanx  sbm
