I've taken the cover off, and noticed the battery seems to be
leaking slightly:

There's a white furry deposit around what I assume to be the
battery - the blue thing centre top. The underside of the circuit
board looks fine.

Is a replacement straightforward? I can solder after a fashion.

A recommended source for a replacement? A google search throws up
quite a few options.

Would I be best not using it until the replacement's in?


Phil is right but I would wait until you have extracted it before
buying a replacement as it could be Ni-Cad or Ni-MH depending on the
age of the tuner, and they require slightly different charging
regimes. Equally it could be 3V, 3.6V or 4.8V although I would admit
that the size suggests the latter.


OK, will do, thanks (and Phil).

You can removed the battery and clean the PCB and then continue to use
the tuner - it will just not remember memory settings when powered
down. Having said that it takes little power so you could just leave
it switched on. Do however make sure that the battery wires are
insulated after you remove the battery but before use. Also take care
unsoldering - remove the negative (black) first so that if you
accidently short the positive to chassis northing will happen: Ni-MH
batteries (if that is what it is) can supply quite a bit of current
for a short time.

Have a look at

who stock just about every type you might need. Maplins also stock
some but only a limited range and possibly a bit more expensive.


Great, thanks.

However, another problem. The tuner is new to me, and I'm told it was
working quite recently. However, I can't get any sound out of it. The
signal bar is showing 7/10 and the stereo light is on, so I'm guessing
that's enough?

Also, the memory store (hold Tune down and choose a preset) isn't
working. I'd think this might be down to the battery, although the
previous owner's presets can be recalled quite merrily - most with a
5-6/10 signal.

Might this be to do with the strength of the signal - I'm just using a
table top FM aerial. Or something more serious, do you think?
