I've got a problem with the sound on my projector.This Revue Lux 80 stereo machine is the same as the Chinnon SS1200 (i think}.The problem is that the sound on track 2 has gone.I was recording the soundtrack from track 1 to track 2 and on playback there is no sound.I thought it might be a speaker but when connected to the stereo it only comes out of 1 speaker.When i ran the film through another projector the sound had recorded.Has anyone got any ideas?thanks Mark.

Is the machine in the stereo position or mono? Can't recall what this actually does to the twin track sound but thought I should point out the obvious.

How about muck on the head? Get in there with isopropryl alcohol and a cotton bud.

Knackered channel on the pre-amp.

Demagnetize the head, maybe?

Hi Mark,

As I commented quite a few posts ago about magnetic recording, heads and the like, you have troubleshot it as you should by taking the film to a known good projector and found that the 2nd track was indeed recording as it was supposed to. As I mentioned in the past post, the most critical aspect of magnetic track recording is the record process. Worn or dirty heads or badly misaligned heads will impact dramatically on record and to a lesser extent on play back. The fact that you got recording says that pretty much the heads, record bias and most of the preamps are OK as these are common to both record and play back (with the exception of record bias).

My suggestion with no playback is one suggested often here by Kev and many others and that is to go in and out of Record several times with the switch. These switches, in addition to shifting the electronics around from one function to the other, also shift the head input/output as well. This is an extremely small signal on playback and the slightest bit of tarnish or switch corrosion can stop one track or the other from doing it's thing. These are not new machines and typically are mostly used in playback. The switches will most definitely dirty up after awhile.


Try it 15 or 20 times to see if you can get track 2 playback restored. Might just work. If that doesn't do it then the problem probably does go to a more complex electronics issue.

Rick, Spot on. As you say if that doesnt work then it must be another more in depth problem.


GS1200 Xenon with Elmo 1.0...great combo along with a 16-CL Xenon for that super bright white light.
