12V Parenthesis? Regulated power?

[jay.stanley]

I noticed that The lowest rated chip in the parenthesis is the 15V LM308. Has anyone tried running this thing at 12V? Or swapping the lm308 for something with a higher max voltage?

I assume it would be like running a rat at higher voltage.

What about adding a regulated power source to vcc? Right now it is unregulated from the wall.

A couple of thoughts:

1) Your power block had better be regulated or it's gonna cause you grief. You need clean, reliable DC power.

2) The LM308 is rated for ±18V supplies, means 36V if you go single rail.
