ba662

[Karl ALEXANDRE]

	Hi all,

	I'm writing you cause i just finished my 303 clone this weekend and I have a problem
	with the VCA. I replaced the BA662 with a CA3080 and a npn follower (i have no chances 
	to find an original ba662). I changed some resistor (r124,r125) values so the input 
	voltage swing does not exced 10mv peak to peak, but i have some very anoying unilateral 
	cliping. I added a bias trimmer to ota, but no way, i can reduce the cliping, but i get
	a sort of dc offset whcih changes with the CV (some CV feedthru ?).
	I'm not very familiar with OTA design, and would be quite happy if someone can help me.
