DIYbanter - JVC XR-330V - receiver preset memory lost

I understand that there may be a faulty capacitor causing preset
stations to be lost when the unit is powered down. Can anyone point me
to where on the board I should be looking?
Also, if someone has a manual they can email that would be great.
Someone tossed this receiver, but it works fine except for the preset
and the bulb that illuminates the radio display. TIA

Usually, if a receiver's station memory is capacitor backed, it is a
"GoldCap" type that you are looking for. They are normally located up with
the system control / display processor on the front panel pcb. Most are
green, and short and fat rather than tall and thin. They are about the size
of a dime if you are american, or a 5p piece if you are UK. Probably about a
quarter inch tall. They actually look like a little coin cell stack, except
both legs come from the underneath. The value stamped on them will be
typically 0.5 to 1F at 5.5v. Make sure that it does say something like this
on it, as sometimes, backup really is with a tiny NiCad battery cell stack,
which looks very like a GoldCap at first glance. If you Google GoldCap or
"backup cap" I'm sure you will find a picture somewhere to point you in the
right direction.
