Just inherited a TEAC X-7. It came with a 4 track alignment tape, but the machine is a half track. Before I start adjusting the heads, will this alignment tape work on a halftrack machine? I'm new to analogue, so any help would be appreciated!
Thanks guys!

congratulations! I own a 16 track (actually 2 ) and a 8 track, and I'm gonna hazard a guess and say "probably not" I believe this tape should put out a calibration tone for each track and you'll be picking up two tracks (or portions there-of) on each half track... and I'm not sure how you'll tell which is which... but I suppose it could maybe work...

half tracks are much more forgiving than a 1/2" 16 track machine

I'll see if I can attract Beck's attention elsewhere, he may be able to help here.

Cool

Unless itís been modified with new heads the TEAC X-7 is quarter-track stereo (two tracks in each direction). A half-track has two tracks that use the entire width of the tape in one direction only.

As for the calibration tape, it depends on the brand/model of the tape. MRL and most TEAC YTT test tapes are recorded full-track, so what you have could be used regardless of the track count, as long as the speed and equalization of the tape are right for the deck.

Let us know what model the tape is and I can tell you for sure.

That tape is right for the machine, but AMPEX calibration tapes are pretty old, so it might not be in the best shape. The tape will work for calibrating the high speed (7.5 ips) for normal position tapeÖ and of course will be all you need for aligning the heads regardless.

Yeah, it looks pretty old. But plays fine. Thanks, man!
