Sorry to hijack, seems like an appropriate thread for this question:
Just got my drill press and blank pcbs

!!! I want to build this but my perfboard version was kinda a failure, passes signal with some tone change and a bit of diode clipping, but no oscillation. This circuit is fairly complex for my skill level, but it is my hope that pcb will be the answer as I am too frustrated to continue debugging the perf version.
So the question is:
On the ROG perf layout there are (2)TL062 ICs, where on the Andre Schaap/John Lyons PCB layout the (2)TL062s are replaced by (1)TL064. I have the 62s but no 64s. Can I use (2) TL062s instead of (1) TL064? (crosses fingers and hopes answer is yes)
Thanks in advance
