Hello.  I have an Afterlife, for which a TL072 opamp is specified.

I think that my chain might be improved by having a TL072 in it but I've always had drive problems with TL0 op amps.  I would never connect one to the output jack of anything.  This is repeated experience talking.

So here's the Afterlife and here's one side of a TL072 pumping up control voltage into a 100uF capacitor.

Has anyone noticed any problems with this?

Thank you kindly.

Hello.

Should I be concerned that standard pedalboard wiring has positive voltage on the outside of the connectors?  The panel-mount jacks that I am aware of have the outside terminal "grounded" to the chassis.  So your whole system is positive ground, which I guess is okay if there isn't a nine volt negative ground anywhere in the system.

Right?

I've always been a little uncomfortable with misleading abbreviations.  For instance, when Madbean says to use a 100kA pot, does that mean 100k Audio Taper, or does that mean 100k "A Taper" which if you look it up on a pot data sheet might mean something completely different?

What does it mean really?

Thank you kindly.

One would think that if germanium is good for the rectifier diodes, Schottky would be great.

Does anyone have any experience along these lines?

Thank you kindly.
