Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany

Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.

This manual is very good. 303 pages scanned in a very high resolution. My camera has bad, leaking capacitors which all of the V5000 models are suffering from these days.
There is a huge part list with all capacitors, transistors etc. in this manual which helped me a lot. Otherwise I would not have been able to buy replacement parts.
The dissassembly guide is very enormous and detailed. Unlike on the Panasonic MS1 manual I downloaded here it actually looks like the real parts look. And the screws are labeled correctly, so you shouldn't have any left after the repair. ;)

has all the schematics you could need,and very well laid out format also has all part numbers along with an exploded view which is helpful

Very nice to have! Now it is no problem to understand how it is put together.
Helps me a lot.
KX-FP320G / KX-FM330G
The following shows the operation of this circuit with the simple circuit. The circuit in the previous page, when the transistor Q101 is ON, secondary rectifier diode D201 is OFF and the energy is charged in the transformer T101. Q101 continues being ON while the voltage is generated by control winding (B). Q101 is tuned OFF by control circuit, then each windings of T101 changes the polarity and rectifier diode D201 truns ON. The charged energy of T101 supplies power through D201 to output load. And the voltage of control winding is decreased and Q101 contines being OFF state. When all energy is discharged through D201, Q101 is turned ON again and it makes the polarity of each windings of T101 in reverse and goes to self oscillation. When input voltage Ei is high, the operation frequency is stopped up, and when load current is high, the operation frequency is stopped down.
Because of the repetition of this operation, the voltage, which is stepped down by winding ratio of transformer, is produced at the secondary side of transformer. And after rectified, it´s supplied as a DC voltage. [Control Circuit And Error Detecting Circuit] Error detection circuit compares 24V output with the internal reference voltage, and transmits this error signal to control circuit of primary side through PC101. The control circuit drives the main transistor Q101 and controls the ON period according to the error signal in order to keep stability of output.This is shown as follows. When the output voltage of 24V circuit steps up, the current of photo coupler PC101 increases, the pulse width of gate signal of Q101 and the ON period of Q101 becomes shorter. [Over Current Limiter (O.C.L.)] IC101 rectifiers the highest voltage with resistors R105 detecting the current in the primary side. When the current is supplied higher then the highest voltage, it switches to latch mode which stops oscillating.
