Put a scope to the record signal path and see, where the signal gets lost.
If your deck has the switch at the bottom plate, give it a shot of contact cleaner (NOT WD40 or such nasties) and exersize it a bit.

Also check that the bottom plate is fitted and properly grounded.

Hi Martin,

Thank you very much for taking the time. I only have a partial owners manual and was not aware of the switch on the bottom plate. After cleaning this switch the machine now records tones in both channels. Thanks. Unfortunately it didn't solve the auto calibration problem. So here is the situation with a little more detail. When trying to auto calibrate the "Record Cal" and the "Record" lights on the front panel flash. But the auto calibration never stops. I have tried several different tapes with the same result. I have cleaned the heads properly. When I listen to the tape afterwards I can hear a single recorded tone repeated in both channels (Both channels now recording after switch cleaning). Are there supposed to be a few different tones? Or just one tone recorded? Any further thoughts on where the problem might be?

Also if you don't mind, A couple more questions.

The partial manual I have doesn't mention the switch on the bottom. What does this switch do? Is it just for recording gain? Where should it be set? The switch says Din and Line.

One of the lights in the machines meters is out or not lighting. Do you know if this is an easy fix or does the entire meter need to be replaced?

Thank you so much for your time and help. It is greatly appreciated.

Sorry spoke to soon. The right channel went out again. More cleaning of the switch has no effect. Also I made a din to rca cable to try out recording. Trying to record from the DIN on the back does not work. No signal either channel. So I switch to the DIN on the front. If I put the switch on MIC then I get a recording in the left channel only. If I put the switch on AUX I get nothing.

Thanks again for any help.

Hi Martin,

I have this exact same problem with my Beocord 9000 now it is fresh back from a complete overhaul! 

All functions do seem to work great, apart from calibration sequence never ends... Can that be caused by bad grounding etc?

Cheers,

Jon

Hi Goodrat,

I wonder, did you ever fix your never ending calibration issue? I have exact same thing with mine, even though it's just back from a full professional service.

Any ideas?

Cheers,

Jon

Hi Jim,

I'm sorry but I never figured out what was wrong. I am just using it for playback and it sounds great. Hopefully someone here will reply with more suggestions. I would love to get mine working as well.

Sorry I couldn't be more help.

Hi,  I have the same constant cal occurring with my Beocord 9000.  Did anyone figure out the problem?

Thanks, Terry
