LM13600 osc asymmetric at very low freq

[Paul Perry]

I asked about this a while ago....
today while going through my oscilator folder found an article from 
ETI mag Dec 1978 with a CA3080 based osc.."At very low currents the triangle
waveform may become very asymmetrical.This is due to current mirror 
mis-matches inside IC1 and this device may have to be specially selected for 
continuous symmetry".
