Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

On youtube you can find an interesting video by Golt! on battery leakage in
synthesizers and a little bit about the chemistry involved. The electrolyte
combines with the metals on the pcb, such as the copper traces, tin IC pins,
etc, so it's not just the electrolyte you are cleaning,

Glad you found the issue.
