This SMD electrolytic can't be mounted on a side and vertically it would interfere with the mechanism. I would use something like this instead:...
It's not uncommon for leakeage to corrode traces on these models. Seen breaks at the contact between trace and capacitor pad, usually not visible...
Yes, sparks at the commutator are always produced because the windings of the rotor act as an inductor: it charges when powered, then stores...
Haven't worked on this model before, so not sure what is the reason capacitors were replaced. If caps leakead on the PCB, it's very likely there...
Do you have a W&F measurement screenshot from WFGUI ? The pressure motor spindle puts on the rubber disc is given by the spring tension. If that...
The whirring noise is likely coming from a worn capstan ring, it's quite common on D6/D6Cs to be loud in operation for this reason. It's why I...
The ticking is likely back EMF from the motor (from sparks at the commutator-brush contact). Fact a larger belt eliminates the problem means the...
30Hz difference can be considered in spec. Even the manual gives +/-1.5% REV speed differnece, which means 45Hz. 30Hz is just 1%. Yes, W&F can...
This is very disappointing in regard to the new gears. I suggest contacting the seller and let him know about this problem, as it seems very...
Replacing only the rubber tire I do NOT recommend, because almost always such roller assemblies become eccentric. Generally speaking, don't...
You are sure it's slipping on the hexagon and not on the shaft ? It's possible the hole of new gear is slightly larger (to avoid cracking), case...
It seems this D6C may have more than one problem: - the high pitched whining noise; given it's realted to removing the 2 ground screws, it's...
First of all, keep in mind you need to allow some time for the unit to stabilize (5-10 seconds) before reading the speed/W&F figure. In the first...
Now in practice brushed motors will last a very long time. But if a walkman is used like 5h a day, every day, the motor will eventually fail after...
Yes, as stated in previous post in phase --> 45 degree line, but: 1. You need a full track test tape (meaning recorded on mono head); 2. On such a...
Regarding Lissajous curves, there are many patterns depending on phase and frequency difference between 2 signals (in case of test tape there is...
Not sure I understand what you measured with the scope, are you reffering to azimuth ? XY 45 degree line means the channels are in phase. For...
The VU-meter peaking may be caused by imperfect contacts in the REC/PB switch. That should be cleaned. Also, has this unit been powered with...
Demagnetizing the head won't solve the lack of HF, as it's a problem that exists only on one side so it's a tape path problem. Head azimuth is...
Pinch roller backets simply pull up, but there is a bit of force required. Use a flat screwdriver underneath the bracket to pull the roller...
