Sony Video Recorder (Reel to Reel)

[malcolm george]

Please can anybody help. ~I have a Sony-Matic reel to reel video recorder.
It records and plays back video fine but I cannot control the audio level
during recording. and the AGC does not work. Does anybody have a circuit
diagram or service manual.

Any help much appreciated,

I have service manuals for all the NTSC Half-inch Sony open reel
machines. A Pal version would be slightly different but what model do
you have?
