Hello I have recently acquired a Tascam 414 MkII
The unit is in really good condition both inside and out, the only thing that looked worn out were the rubber belts which I have since replaced.
Everything works perfectly tho track two does not seem to record to tape, or rather, play back what has been recorded.
When monitoring live track 2 the VU meter lights up and I can monitor my input perfectly. When I go to record through track 2 nothing is recorded.
I have traced continuity on all the wires leading to the record and play head, all are fine.
I also did the trick where I recorded on all four tracks and then flipped the tape over and played in reverse. It seems track 2 is able to record after all because I had what was recorded on track 2 playing on track 3, but what was recorded on track 3 was not able to be played back on track 2, the VU meter would not work at all and no output was heard.
So I guess the short has something to do with playback from the playhead?
Do you have any advice on how to continue diagnosing this? The board looks basically spotless and no caps look busted, no leaks, no solder messed.
I feel like i'm so close and just need someone with more experience than me, hence why I am reaching out here.
Does anyone know where I can find a schematic? Could it be a bad IC? or broken op amp or something?
Thanks for you time,
Can post pictures and answer more questions, Thank you!
