Subject: Re: Monopoly VCO-4 prtamento/detuning issue

Hi,

Ok, I understood that I have the older revision of Monopoly, that;s why I do not have the KLM398.

Today I opened the case as promised, with care.
You can see the picture: http://tinypic.com/r/v3oq4i/5

Of course I can only replace the 4066 chips which both are socketed.
The second one is under the cable.

Is the TL072CP under the capacitors (inside the circle) ?

Portamento works perfect to the other VCOs and can be adjusted from 1 to 10. Only in VCO4 it is always on and cannot be adjusted.

Do you suggest to replace the TL072 or I may have a damaged 4006 ?

Second question. As VC04 is also detuned about 4 notes and I do not have the KLM398, which are the switches for the 4rth VCO that I have to tune ? I show two white circle tuners under the fourth VCO (check my uploaded picture).
