Hello

I am sure this is a classic issue, but it just happened to me now, and I
need some advice.

My P6 has not been used for a while, and since electronic equipment
should be turned on once in a while, I pulled it out to give it some
time turned on. But in the meantime it has developed an issue with the
scaling of the octaves. Every octave has become about a semitone too
wide. All the oscillators line up fine across the entire range, but the
range is just scaled wrong.

I read suggestions that it may be an issue with an opto-coupler, and if
that is the case, where is it located, and what modern day component may
replace it?

If it is something else, please give me your suggestions.

And before you ask, the battery was replaced long ago, before it got
bad.

Thanks

Frank Carvalho
