Help with 1967 Ampex 440 4 Track Machine

I'm refurbishing an old Ampex 440 4 Track tape machine. Two of the 4 channels don't respond to an input signal. What are some of the things I can check to diagnose the problem?

Need a lot more information before anyone can give you any advice. (what you are asking for is akin to "my car is not moving what should I check?)

You might also want to post this request at the Ampex List Serve here [email protected]

Best of luck.
