Specs on op amps include a + voltage and a +/- voltage min and max. If I measure between pin 4 and pin 8 I will be measuring +/- V, correct? If so it would be a push pull PS and I should be able to measure half the total voltage from either pin 4 or 8 to chassis ground at the RCA, correct? Someone told me -Vcc was ground and it looks like that is incorrect. Thinking about OPA2111 vs OPA2107. Thanks, Tweaker

Yes.

Both Opamps you named run from "push pull" PS.
There are some Opamps that run from "single ended" PS.

When looking at +- V on the Burr Brown spec sheet for the 2107 max +-V is 18v. When looking on the TI 2107 spec sheet Total max voltage is 36V. So it looks like +-V refers to one rail not the measurement from pin 4 to pin 8 which would be total voltage. Somewhat confusing. T
Thanks. It's pretty obvious but I wanted to make sure since someone told me that V- was ground. T
