converting BGW 750C to BGW 750B VU meter PSU hock up

[bonesbiggis]

hello

I am rebuilding my 750C into a 750B.

I have rebuilt the vu meter in kicad but am a little confused about
the hock up of the LM324 ?

from what I can understand it is the LM324 ic pin 4 to +15V and pin 11 between R527 and D507 ?

would be really happy if some one can confirm i am on the right way.
