Any idea why the LM833 is used at the end of the circuit (following the PT2399) instead of a TL072?

swyse Well-known member Jun 30, 2022 #2 Just a guess, but my guess would be because its better at driving a load like a long cable.
L lukegalea Member Jul 1, 2022 #3 I'll try comparing the datasheets again. The LM324A is necessary because of the common mode input voltage.
