Sony vintage stereo casette tape TC-D507

It will be very difficult to find that exact input voltage per connector pins from this casette tape.

I have not the amplifier (TA-D507) wich feed external with power this casette tape. The input power connector (system control 2) are 15 pins, from wich are used seven pins.

Thanks !

 

There is an AC input feeding a bridge rectifier with smoothing capacitors across the output. This rectified voltage feeds the power pins of !C701, 8 and 4. Those pins have the measured voltage marked, namely 12.1V and 11.9V. So the peak AC input is greater than that 12V by the diode voltage drop of about 0.7V i.e. 12.7V peak. To convert the peak of a sine wave to RMS divide by √2. This gives an input voltage of approximately 9V so the transformer needs to be a centre tapped 9V-0-9V (or two separate 9V windings connected in series).

Please allow me to repeat. So, for the second pin of connector feeding -9 volts, for the third pin feed the ground and for the fourth pin of connector feed +9 volts. For the five pin which in the drawing is (BUS GND), for the sixth pin which in the drawing is (V BUS) and for the twelve pin which in the drawing is (NC SYSTEM GND) makes no power supply. Thanks very much Bela.

The power input is intended for AC. If you want feed it with DC then it should be ±12V. The AC input also feeds D710 and D711 but you have not included what the part of the schematic that shows where those diodes are connected so I cannot confirm that this circuit will work properly with a DC input. To be sure, please show more of the schematic.

 

You need a 10-0-10V AC transformer, according to the service manual, a 9-0-9V will do, it has to be AC as the ac voltage is sent via diodes D710/711 to the processor IC801.

 

Thank for all. The service manual are in attach.

 

The TA-D507 amplifier service manual, amplifier witch feed external with power this cassette tape.

 

Yes, it's terminals 16,17,18....

Hi I have no electrical background but love old ekectronic appliances like the Sony TC-D507 Tape Deck.

I would like to power it up but not sure where to start.

Thanks Louis
