very helpfull
circuit diagram and sparepart list available
;
Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.
;
It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

HANDSET SECTION
3. Checking TX output Setting:
peak power meter + � ANTENNA TERMINAL
� Make the set in Test mode (see page 24) 1. Checking RX I&Q Output Level Setting:
oscilloscope + � level meter + � TP520: RXIP TP521: RXIN TP522: RXQP TP523: RXQN TP553: GND
Procedure: 1. Place the handset in the Continuous Transmit mode (CH1, High power). 2. Measure the ANT OUT output of the RF module in the handset using a peak power meter. 3. Confirm that the measured output is 62 mW (MIN 25 mW). 4. Also, execute steps 1 through 3 for the channels 10 and 20. CH10: 64 mW (MIN 25 mW) CH20: 64 mW (MIN 25 mW)
SSG
ANTENNA TERMINAL
Procedure: 1. Place the handset in the Continuous Receive mode (CH1, LNA, AGC ON). 2. Set the SSG frequency to the frequency on CH1 + 300 kHz, and the RF output level to �95 dBm. 3. Measure the output level of RXIN, RXIP, RXQN, and RXQP with a level meter. At this time, confirm with an oscilloscope that a sine wave of 300 kHz is output. 4. Confirm that the measured output level is �25.0 to �19.0 dBV. If IC502 was replaced (there is no ID data), the output level is �30.0 to �24.0 dBV. 5. Also, execute steps 1 through 4 for the channels 10 and 20. * For the frequency on each channel, see page 18.
2. Checking TX Center Frequency Setting: � short: TP555 � TP553
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Short TP555 and TP553 (GND) on the HAND MAIN board in the handset. 2. Place the handset in the Continuous Transmit mode (CH1, High power). 3. Measure the ANT OUT frequency of the RF module in the handset using a frequency counter. 4. Confirm that the measured frequency is 903.600 MHz ± 27 kHz. 5. Also, execute steps 1 through 4 for the channels 10 and 20.
