I've done a bit of surfing for more info on this. BTW, it was the
batteries that power the synth (D-cells, I think), not the internal
lithium cells that have leaked.

It seems that the most likely cells to leak are Zinc-Carbon, since
the Zinc cathode forms part of the casing. The gunk that leaks out
is mostly Ammonium Chloride, which forms a weakly acid solution in
water. Bicarb sounds like a good idea, since it's weakly alkaline
in water, so I think I'll give that a go.

I'll let you know how I get on, but I'm currently finishing off
another project (a JHS Harmonizer, which I'm very proud of) so
it might be some time before I get around to it.

Cheers
