So I am a novice with electronics, please bear with me.
I am trying to restore a Sony TCK-33 cassete deck. The mechanical part is done and only the calibration is needed. The left side is significantly lower level than the right one. So I would like to do the calibration procedure as the service manual suggests.
It demands for some cassete tapes:
WS-48 (3khz, 0dB) Speed cal.
P-4-A81 (6.3khz, -10dB) Rec/play Head azimuth, phase check.
P-4-L81 (333), 0dB) Playback level.
I am wondering f at least for some of this tests, a cassete to 3.5mm jack could be used so I can generate signals with a phone.
