TDK HD-11 Tape-Head Demagnetizer: Teardown, Reverse-Engineering and Experiments

[@I967]

Quite an engineered piece. I have a book about tape recorders from 1966 which suggests complete and perfect demagnetization of a tape head by a means of discharging a capacitor directly into it. The reason it gives is that the tape head is not always ideally accessible by a handheld demagnetizer. I am now trying to find out more about this technique. Thank you for the video.

Wow!. Impressive reverse engineering. It helps me understand how this device works !!! Good work Roger / KainkaLabs I find much to a circuit electronic photographic flash. It could change one to do the work of degaussing?

Awesome!! Could you please share again schematics? And do you know witch type of transformer is T1 component? Thanks a lot!!

Try this link: 1drv.ms/u/s!AmW9-q-1GZM1iNcJD6AJ0vArJhGm1A?e=oHjAAO And I don´t know, the type of transformer.

Thanks for the nice video, i would like to ask you something....some clarifications regarding the operation..... selector on ON, I wait a few seconds for the green light, then what do I do? Do I push the button several times to do different areas (head, capstan)?.....or do I push the button and hold it along the area? Grazie

[@KainkaLabs]

Yes. Every time you demagnetize one part, you remove it from that part, recharge until the green LED lights up again and demagnetize the next part. The demag-action is only around 1 second when pressing the trigger switch.

Wow😮😮😮cuánta ingeniería en ese depilador de cabeza 🙏🙏🙏tank You exelent movie😑😑😑

What was wrong with it to do all this respected job ??? I mean what was the symptoms happening to discover that there was a problem with it ?!

[@KainkaLabs]

I was just curious how it works. Nothing was wrong with it.
