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).
