Overdesigned VU Meter Buffer Amp

.

I did a quick search for MC624 and did not get a good idea of what that is.

24v is marginal but probably OK for a unity gain buffer. What are the rail voltages of the source circuitry?

True VU meters are typically 600 ohm loads while TL07x op amps are only rated to drive 2k ohm loads.

Good luck... errors from marginal rail voltage*** and inadequate drive impedance may not be noticeable in typical use.

**** I learned this leasson the hard way trying to drive true VU meters from a 12V meter bridge supply. The customer noticed the difference and the customer is always right.  :-[
