    US-144 MKII interface
    Been using the same tascam interface for a while now, but only recently I've come across a pretty major problem when trying to record analog: an intermittent yet frequent crackling occurs when I plug in a mic or amplified instrument. I know it's not the cables themselves as they work fine with when just using them with amplifiers and I know it's not the instruments as they too work in all other situations.

    I noticed that pushing the cable at the interface input fixes the problem, which could indicate a cable issue, but seeing that my instrument cables work with other devices, this should mean that the problem is in the interface.

    In conclusion:

    1) Is it worth it to try to fix the inputs on the tascam, or should I buy a new interface?
    2) Are there any possibilities I missed?

    I have no experience on 144, but according to your description of the problem i would quess it's one of two possible problems:
    a. dirty connections: just spray any "contact cleaner" stuff into the input jack
    b. bad solder joint: anyone with elementary electronics skills and access to a soldering iron should be able to fix this
