Picture
Manufacturer:    Yamaha, NIPPON GAKKI CO., LTD. (JAPAN)
Model:                    Tuning Oscilloscope PT-3, S#5049
Vintage:                 1965
Purpose:                Musical Instrument Tuning
Condition:            Working


Comments:
This is an interesting oscilloscope because of its dedicated use. It is specifically designed to check the tuning of musical instruments. 
It was a high tech instrument in the late 60s and 70s. The settings of notes and octave were very convenient for the user.
Unfortunately I don't have a manual, otherwise I would like to bring it back to spec.
