Updates June 6, 2021: Improved the slicing options to result in softer feet Added a much larger version of the feet for increased dampening Description I designed these feet as a 1:1 replacement for the original feet on the Tefi KC-1 Ra.…
The original ceramic pickup cartridges of Tefifons are made from a material that absorbs moisture. Therefore, almost all of these cartridges are now rotten and need to be replaced. Here is a photo of an early attempt of me replacing the…
The cassette drive is a part of the Tefifon that often breaks. Also it is constructed in a way that it is impossible to disassemble without breaking it. Therefore, there is no good way to relubricate the sintered bearing. Many drives…
The original mats of Tefifions were made of a material that unfortunately has not survived the decades well: So I designed a 3D printable replacement part that mimics the design of the original as closely as possible: The key to the…
The drive pulley cap is a part of the Tefifon that is sometimes cracked. Although I didn't need one, I wanted to prove that a replacement part could be made using 3D printing techniques. So I designed this replacement part. Original:…
If you replace the pickup cartridge on a Tefifon (like here ) you might find that the tracking force is too high. The adjustment range of the original mount for the spring/dampener-combination is limited: So I designed a 3d printed…
The drive pulley is a part of the Tefifon that rarely needs to be replaced. But I have a pulley that had a deviation of 0.3 mm in concentricity. So I designed this replacement part. My first print only had a deviation of 0.06 mm in…
A drop-in replacement part (right) in the same design as the original part (left): Printing I have printed the part using white PETG in 0.15mm layer height. Prints without supports by using the standard bridging-trick (requires 0.15mm…
The original mats of Tefifions were made of a material that unfortunately has not survived the decades well: With another project I have already published a way to print replacement mats, that are fine. Now with this project I provide a…
Update June 27th, 2022: In the meantime, I have also found another way of bonding silicone rubber without the chemical treatment trick described here. I have added the description of this alternative at the end of the article. Preface…
Changelog: June 24, 2021: After working with the mounting rack in practice for a while, I have significantly optimized the dimensions. In particular, it is now much taller, so that there is also enough space for the motor underneath. Now…
When restoring some Tefifons, I wanted to install a preamplifier in the original case. There is more than enough space, but no obvious mounting options. Of course, I didn't want to drill any additional holes in the unit. So I came up with…
When restoring old Tefifon units I found it very difficult to work on the chassis without damaging the delicate parts of the device. So I designed this simply mounting rack. Simply print 4 corners (2 of each kind, PETG, 0.3mm layer…
