K5synth

they must fit exactly

The biggest problem is the pinout(If I remember corretly, about any 
opamp can replace a TL0xx). I saw a couple of 14pin opamps but some were 
2 chans, some not the same . . .
If no other opamps can fit, filtering the 6v input(Noise is heard only 
when the K5 booted up and the PSU's 6v is always on when you turn on the 
switch) of each opamps might fix the problem.(But the traces bring the 
current directly to the chips, without any components between, which 
makes it difficult to filter.)
