I don't think you should see anything on either terminal of C211. Try paralleling another cap of the same value across it to see if it makes a difference.
Anyone who purchased the repair tutorial, email me (babin_perry@yahoo.com) if you want to download the latest version.

I believe I've found the problem. After much troubleshooting of the signal feeding the differential amp circuit, it seems that C223 is faulty. Bypassing that cap results in the right channel outputting the same gain/level as the left channel (and same clip point).

Thanks for all the help!
