Not sure if you are still looking but I may have a schematic for this amplifier. Send me a PM if you are interested.
I recently came across a pair of these Schulmerich Carillonic 6-228. Question for Zap I am looking for schematic if you still have one available. I can't find much information on these amps I just ran across the thread and though I would ask. Thanks
