Hi friends, I'm looking to get my old 244 back to tip top shape. So far I've replaced all rubber parts (almost lost the pinch roller arm's C clip...dang that thing's tiny and likes to shoot off!) and pulled each mixer board to clean the pots/fader/switches. Transport is now stable and working, but the record levels and bias seem a little out of whack, so I'm hoping to score a service manual for schematic/calibration info. Unfortunately every old link to a 244 service manual is dead. Anyone have a pdf of the Tascam 244 Service Manual they can share with me? Thanks!
