Adam;
I would look at the caps in the 10v regulator area and make
sure they are "modern" newer capacitors, the other thing is that
there was a mod on some IFAS boards that had a capacitor in the Audio
transformer feedback loop that was changed from a cap to a resistor
or from a resistor to a cap ( do not recall which off my head) .. if
you study late IFAS board manuals, you can find the correction.... I
have seen excessive heat and current in the 12v audio PA area of the
receiver if this mod was not done ( in other words if you have and
early IFAS board) in any case I would exchange it for a newer one if
in doubt..... as it can cause excessive current draw... as it is one
of the few things connected to 12v in the receiver...The other thing
is make sure the feedthru area for the 10v reg has adequate clearance
where it leaves the osc multi board heading for the front end..
incorrect alignment or bent pins could short out and blow the fuse....
Did the fuse BLOW or MELT.... one is usually caused by a dead short,
the later is caused by over current... charred glass would indicate
blown....little balls on the end of the links would be MELTED...
