Reel deep thoughts...
Hey all.
So I’m tinkering on a Tascam 244...really like it by the way...built like a tank compared to the 424 I’m used to. Anyway, the machine has a problem with no signal getting to tape or off of tape on tracks 1 & 3. I’ve gone through typical troubleshooting to verify in fact nothing is getting to tape and nothing will reproduce off of a known good recording from tracks 1 & 3, and this is true for any input or output pathway on the machine.
I verified the Control A PCB was sending proper control signal to the play and record amp boards, bypassed the dbx board to make sure it wasn’t that...so then I checked the wiring to/from the record/play amp board and guess what? Open coils on #1 and #3. The head *looks* fine...this doesn’t appear to be a high mileage machine and the head condition reflects that...can’t see any open gaps...anybody have any experience with this? I’ve not encountered this before. Cassette heads tend to last a pretty long time. Is it possible for the coils to be damaged in some other way besides wear?
