Glad to hear you finally found the problem ! Did you end up removing the takeup reel as well ? Ask as that's not exactly easy to do and...
The fact motor voltage is higher with load (a cassettte in) is normal, it shows the servo is compensating for the higher load, thus regulating the...
Want to add some feedback in regard to the battery in original post. In the meantime got one and tested it: compared with the 2 x 10440 cell one I...
For this particular application I think most (if not all) test tapes are ok since you won't obtain less than 0.15% WRMS even in the absolute best...
It is a significant improvement for sure. Would be curious to see a W&F reading. Note in regard to speed adjustment there's drift in this...
White lithium grease, although type of grease used on these points isn't critical.
To be clear, by "shaft" I'm reffering to the part of the shaft that rotates inside a bushing. What is marked with red arrows are shafts. What's...

For all rotating parts shafts use watch oil, even if there was grease from the factory. Only part where you need to use grease in on top of the...
The adjustment described is for W&F stability, not for tape speed. They say desolder the bridge (which disconnects the PLL, so no quartz lock),...
Yes, cyanoacrylate based glue (known generically as Super Glue) is good for repairing the reel gears. You just need to add a small drop on top...
Looks factory to me, it's a bodge on an early revision of the PCB most likely. On later revisions they probably added those components on the...
No, it isn't normal. Check the screws where the AAA sidecar is mounted. You most likely installed a long screw in a place where a short one...
You can't adjust the speed since the D6C is a quartz lock unit and speed is determined by the crystal frequency. Only speed that can be adjusted...
That area you press on is where the buttons PCB connects to the main board. This explains why you can realease the pressure and unit still runs. I...
If you want a full kit containing all 3 gears, this has all (but it is more expensive): https://www.ebay.com/itm/314978961246 There's also a kit...
WFGUI is a software to measure wow&flutter and measure/adjust tape speed. It can be downloaded here (first link):...
I attach a picture with motor spindle. Clean both, there's nothing to grease both parts should be clean even from fingerprints. As a sidenote, no...
The carriage activates a lever when door is opened, it's like the STOP button being kept pressed. It's designed to unlatch the mechanism once the...
Diffusion is a part of semiconductor manufacturing process. It's common for a chip to be packaged in a different country from where the wafer is...
