Marantz 2275 fix and rebuild

The BA312 IC is at HE01 and HE02 on the schematic. Does anyone know which one is for the left channel, and which one is for the right channel?

Audiokarma website is a great resource, so many things have been discussed here. My tuning meter was also misaligned, searched the website and found how to adjust it. If I didn't read the posts here, very likely I will use a metal tool to adjust it and will break it. Don't have the tool, cut a small wood stick as recommend by members here and it works perfectly. I should save this wood stick for future use.

Now the only problem is the dial pointer LED light is too bright. It's so bright that it is a little annoying.
