TS-520 Info Needed

Tue Sep 2 11:47:14 EDT 1997

Adam.....FETs arent designed to run HOT!  It's a small signal device and

dosent like heat at all.  So.....you might start out be replacing the
and then see where to go from there.  I think that might be a cure for
sense problem.  There are several replacement Fets that'll do the job
fine, so just cross reference it and get one from NTE or one of the

I sold all my 520 manuals, so I cant make an intelligent guess on the
voltage measurment for you...sorry.

Good Luck
