Technics RS-B105 - Resistors and Capacitors

RS-B105
Dolby NR circuit
1. Test equipment connection is shown in Fig 10.
2. Set a normal tape and apply 5kHz signal in record pause
mode.
3. Adjust by attenuator so that the output between terminal ©
(L-CH) {terminal @ (R-CH)} of 1C401 and ground is 12.3mvV.
4. Turn NR switch ON, and check that the level changes as
specified from the fevel in NR out mode.
Standard value: 8+ 1.5dB
