How many gangs

I have a marantz 115 B tuner, and I cannot figure out how many gangs my tuner has. The service manual and schematic don't shed any light on the subject, and I'm not very electronically inclined really. Can someone out there help a fledgling vintage audio lover get some sleep!

They will have more info there on your Marantz than most other sites.
