Question is about a Kyocera R-851 receiver, ca. 1985, 85
w./channel. Unit is in fine condition (many capacitators have been
replaced) except for one thing: it doesn't remember radio stations.
Does anyone know enough about this unit to tell me what the likely
culprit is here? Any links to schematics?
Look for a .47 to 1 Farad capacitor on the front panel. Used to do
warranty service on these and I believe that is how the back up
voltage was stored. Chuck
Thanks for the quick reply.
So by "front panel" you mean the back of the front panel inside, right?
Would that be accessible from the top or bottom of the unit?
Found it. But it's not a supercap as you said; on the left side of the
front panel there's a 3-volt cell, a Sanyo marked "LF-1/2W" that says
it's a Li-Mn cell (never heard of that chemistry before). I'm going to
the local electronics store to see if they have a replacement.
Sorry about my mistake but it's been 22 years since I worked on one.
