I have a Symmetry ACS-1 active crossover that I want to modify. The writing on the op-amps has been removed. I would very much like to see a schematic or at least find out which active parts are used.
(When I see parts where labelling is removed, I usually refer to it as "antimagnetic parts" or parts modified with "antimagnetic paint" just for fun. It is a really silly practice in my view.)
Your help would be much appreciated!

If the opamps are DIP-8 packages I would bet they are standard duals. How about measuring the voltage on the pins and seeing if 8 is +ve and 4 is -ve?
No op amps in this crossover but dual and quad jfets packs
