[sdiy] MS20 VCF clone troubles

[Frederic Bourgeais]

Hi all,

> Fred: 3080 are connected to -15/+15, but i didn't linked the bias amplifier
input (pin 5).. Should I ground it ?

I did the modification yesterday, I connected the bias amplifier input to
10k resistor that comes from the current sources PNP transistor, but no
way... Perhaps 3080 are fry.. I'll Try to changed with another new ones...

thanks for your help, I'm sure it will work :)
