It sounds as if you may have a cracked PCB track or an earthing problem. Cracked tracks are often very difficult to see on a D6C, even with a good...
If the motor is running in stop mode, that is not a good sign. It is one of the symptoms of a failed CX20084. However, before writing off the...
At this stage, you need to remove C606 and test it out of circuit.
You are not measuring across C606. You need to refer to your PCB layout. You are actually measuring across R608, which is a 10k resistor. C610 to...
What have you used to power the D6C? Did you use batteries or any type of DC adaptor? The motor controller chip (IC601) is very easily damaged by...
I do not recommend using the cue and review functions with the head pressed onto the tape with the FF or REW button pressed. I have seen a few...
I have seen one or two D6Cs with prefix letters in front of the serial number but I have no idea why they were used.
Hi @Kiwinut and welcome to Stereo2go. I have just sent you a PM.
Thank you for the update. Some of the speed problems on these machines can be really strange and difficult to fault-find. Well done on finding it...
Is this the part you are looking for? Sony WM-D6 plate lock brand new remanufactured replacement part: Ebay
The voltage on pin 5 should be 1.65V or somewhere close. If it is low then check C606 first; it may be leaky or short.
PM sent to @Cassette2go.
I have labelled the bridge on the photo. Note that the white wire from the two core screen cable, from the speed tune switch and pot, should be...
The only other capacitor which I can suggest is C608 (3.3uF / 16V tantalum). I had one of these which had failed on a SMD D6C last year. In this...
It sounds as if you have a capacitor problem. When you have the speed tune switch set to "On", does it start at the correct speed and stay at the...
You should check the ESR of C601, C602 and C603. These are the electrolytic capacitors on the FG amplifier circuit. If these have gone high ESR...
@retrocode.kr Good luck. Take care and take your time.
It is also worth removing the remain of the potting from under the pins of the CX20024. You may need to put the CP602 back into some acetone to...
From my measurements I believe the values of the capacitors shown are: 1 - 2n2 2 - 180pF 3 - 2n2 4 - 10nF 5 - 10nF 6 - 3n3 The missing diode was...
