Good morning,
I am trying to fix a tape tensioning problem on an MCI JH 16 analog torque board.
There are 26 socketed 741 op amps of roughly 10 different model numbers. Is there any difference between models numbers 741C, CN, CP, or CP1?
Mouser has a good deal on some Texas Instruments UA741CD at 19 cents each.
Is it most likely that MCI would have used all the same model number when the machine was first made in the 70s? If so, that would tell me a lot of these have been changed over the years.
Thank you,
William
