Need service manuals for Nagra SNST (reel recorder) and DSP (playback unit)

[david winter]

Hi,

I'm looking for the service manuals for:
- Nagra SNST reel recorder (not the SNST-R but the usual SNST)
- Nagra DSP playback unit for the SNST

Both are not working. The recorder outputs some DC and the amplifier outputs nothing.

Thanks !


David.
