Description
DescriptionAll my products are 100% Authentic. (Input Selector Toggle Switch) Check AUX, OK. Phono Phono switch push switch 1 and 2, OK. (Input sensitivity switching range) 1.5 mV, 3 mV, 6 mV, switching was OK without any problem. (Pickup load switching range) 30 k?, 50 k?, 100 k?, I could switch without any problem. (Input Capacitance Slide Switch) There was no problem at 10 pF, 100 pF, 200 pF. Tuner, OK. Verifying (Tape Plate Toggle Switch) The source and selected signal are output and it is OK. Playback (Playback switching range) Tape 1, tape 2 and tape 3 were able to switch without any problem. Checking (Mode Switching Range) Normal, L, R ?L, R, stereo output was OK. Reverse, L, R ?R, L, reverse stereo output was OK. It was OK to convert L+R, stereo to mono. R, R?L, R Mono OK. L, L?L, R Mono OK. Check (Tone Push Switch) It was OK that the signal was output directly without passing through the deft and tone circuit. In, bass volume, bass is raised all the way to the right, bass is lowered all the way to the left, and it was OK. There was no noise. The middle volume, the middle tone goes up all the way to the right, the middle tone goes down all the way to the left, and it was OK. There was no noise. Treble volume, bass goes up all the way to the right, bass goes down all the way to the left, and it was OK. There was no noise. (Bustone Selector Toggle Switch) 100 Hz, 200 Hz, 400 Hz, and the selected signal is amplified and attenuated. (Treble Tone Selector Toggle Switch) 2 kHz, 4 kHz, 8 kHz, the selected signal is amplified and attenuated. (Low Filter Switch) It was OK that the signal was output directly without passing through the OUT and low filter circuits. 20 Hz, 40 Hz, and frequencies lower than the selected frequency were cut, and it was OK. (High filter switch) It was OK that the signal was output directly without passing through the OUT and low filter circuits. Frequencies higher than the selected frequency are cut, and it is OK. The headphones sound L and R.(Headphone volume) Turn it all the way to the right and all the way to the left. No noise was produced. Check (Tape Copy Switching Ranges) The source and selected signals are REC-1, REC-2, and REC-3. 1?2 and 3, output from the PLAY-1 jacks to the REC-2 and REC-3 jacks. The output from the REC-1 connector was turned off. 2?1, 3, and output from the PLAY-2 jacks to the REC-1 and REC-3 jacks. The output from the REC-2 connector was turned off. 3?1 and 2, output from the PLAY-3 jacks to the REC-1 and REC-2 jacks. The output from the REC-3 connector was turned off. (Meter operation selector push switch) Connect the generators 130 mV and 1.3 V to the input terminal of the preamplifier and check. It was OK with input-0dB and the meter needle at 0dB. The input was -40dB and the meters hand was at -40dB. It was OK when the meter hand is in the 0dB position for output and volume MIX. Check (AC Outlet) UNSWITCHED, IT WAS OKAY.SWITCHED, ON, ON, OFF, OK. (Tape -2, REC/PLAY connector only) I was able to input and output without any problems.The voltage stabilizers are exactly +24.0 V~25.0 V, +24.0 V~25.0 V and +47.0 V~48.0 V.The balance of the output terminals is exactly within ±20.0 mV. I think there will be no pop sound after the protection is released.*When the DC balance does not deviate from the input to the output jack of the power amplifier. The mode switching range, the baston selector toggle switch, and the inside are disassembled to make the contacts shiny, and the medicine for removing rust and restoring strong contacts is applied.(For details, please see the arrow photo on page 10.) The solder of the recording output switching circuit was deteriorated, so it was rebuilt.Meter lamp has been replaced with a new bulb The captured signal is properly output.
