[sdiy] Serge and multiples

[Happy Harry]

Hi Grant (et al.)

The 10mA at 10V assumes that the outputs are limited to
10V.  I assume that the output could be tied (in effect) to
either rail at +/- 15V.  One opamp trying to go to (lets say)
+10V fighting two others at -10V could exceed this.

It will probably not harm the op-amps. But the performance of the
opamps would suffer a lot. I STILL would not tie them directly. Its
a bad habit (unless YOU built the synth personally). What if you hook
it to another synth that is not protected the same way.

With 10K in line... I'd go for it !
