asm1- dirfts on mods.

[e]

Hi all

i have posted the lfo bad influ on the asm.
tnx for all the advices.
as i investigated the drift facts ,and implanted my own build
regulator i (7815/7915) i have notice this new disturbinese in the force 

every pot. that has + to - 15 range and works as the modulator
such as the FC (filter section) pot , or pwm pot.
when the turn reaches the limit suddenly a small shift in the osc, is heared.
i scoped it , the change is measured like 30 to 40 mv shift.

another fact is when i use my lab regulator , this anomaly 
almost dissapear , at least from the hearing range.

tnx 

Aln
