![]() Visually inspected all solder point on channel 2 section of pcb I then successfully replaced the capacitor, put it back together, and prayed. While trying to replace it I actually popped the pcb pad clear off the circuit board! and had to repair it very carefully with copper tape to create a new pad. I reflowed the solder over one of the op amps 'u201' on the board, I also turned my attention to the other point of discoloration, a single 1uf 50v capacitor, it did not look bad in any way or bloated or leaking but there was a slight discoloration on the solder points so I thought best to replace it. On the board I noted two points of interest, some solder that looked slightly discolored. ![]() I'm not sure if thats what fixed it, I also visually inspected track 2 pcb layout as its clearly arranged in a line. I opened up the tascam and sprayed deoxit on every connector plug, both sides. I feel like i'm so close and just need someone with more experience than me, hence why I am reaching out here.ĭoes anyone know where I can find a schematic? Could it be a bad IC? or broken op amp or something?Ĭan post pictures and answer more questions, Thank you! So I guess the short has something to do with playback from the playhead?ĭo 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. 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. I also did the trick where I recorded on all four tracks and then flipped the tape over and played in reverse. I have traced continuity on all the wires leading to the record and play head, all are fine. When I go to record through track 2 nothing is recorded. When monitoring live track 2 the VU meter lights up and I can monitor my input perfectly. 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.Įverything works perfectly tho track two does not seem to record to tape, or rather, play back what has been recorded. ![]() ![]() Hello I have recently acquired a Tascam 414 MkII ![]()
