Hello.
I have a Beocord 1500 deluxe open reel recorder that I bought some years ago. It's working nicely, except that the azimuth settings of the tape heads are out. I was adjusting one of those, and suddenly the spring-plate under the head broke. I replaced it by some custom made part, but now the adjustments are out. And now I can't get it right as I am confused about the heads, as I have no idea which one is used in which track settings. Also the marking of the track selector (2/4 track) is lost, so I don't know which setting is which. So I ask the next:
1) The track selector positions (up/down - 2/4 tracks). Which one is which?
2) Which head is used in the 2 track mode and in the 4 track mode?
3) How could I easily make the head adjustments? I can make a test tape with my other recorders for 2 and 4 track modes. (Record some frequency from my computer to aid adjusting). Recording head is untouched (screws sealed) but the other three are out of adjustment.
