LCA-2B full manual on my Dropbox: https://www.dropbox.com/s/tnpmx4q0laj3nxb/LCA-2B.pdf?dl=0

I don't know the difference between the A and B versions, but it should help.
 
I just posted the LC2A schematics for Amplifier and Sidechain in the technical section.  Its different transformer and gain structure than a LCA2B but they are similar.  I have full manual if you need it but you said you have the alignment section.

Its Variable Mu compressor .  Does not use vactrols.

Thanks everyone! You saved the day!
 
I've been trying to get the multiband compressor SMB-2C schematic  for ages, but to no avail. I'm interested in how they have done, the tube crossovers and the sidechain implementation.
Anyone with a schematic please?

Thanks in advance.

I wouldn't mind having this as well, assuming you mean SMC-2B. We have one at my work and it has intermittent noise issues on-and-off for the past several years and one channel had completely died at one point. I was able to revive the unit and make it quieter for a while with some instruction from Tube Tech but without any circuit diagram (they won't give them out anymore, understandably so), it was a lot of guesswork and continuity tracing to figure out what was what and still didn't solve all of my issues. I've looked a the lca-2b schem for reference.
