Hello,
To a recent repair of my Mono/Poly, engineer had to remove the VCO thermal grease over the chip. Then he replaced it with another compound/paste and for a few weeks the instrument was working perfect.

Now, when I turn on the Mono/Poly the first 3 oscillators come to the same tuning after 10-15 minutes (the most) but the 4rth VCO comes synchronizes with them after 25-30 minutes.

What kind of thermal paste do you suggest for the Mono/Poly
Do you suggest to use this paste to all 4 oscillators or only to VCO 4

Will this thermal paste work or VCOs need a special paste
