[sdiy] Can I use an LM13600 in place of an LM13700 ?

[harry]

If you use it in a linear portamento circuit is is OK... the extra
loop gain will reduce the offset just about totally...
Sequential Circuits did this many times.  I like linear portamento
myself...

I agree (JH) with your assessment if the OTA is used in an
log portamento. Maybe a Vactrol would be a good choice there.
