Ex National (Panasonic/Matsushita) domestic tape machine
I am very much "into" sustainability, a complete tape machine represents a LOT of embedded energy and to waste that embedded energy is a very bad thing, even worse is to bury it in landfill and subsequently poison our environment!
What is embedded energy?
Embedded energy is a measurement of the total energy that was used to create a component, a module or a complete piece of equipment originally.
So why has this National RS-760S become an "organ donor"?
Keep in mind this was a machine intended for the domestic market, the price conscious consumer. A fun machine to play around with (NOT for the professionals) but the Japanese decided to use sprocket reel tables which are partially made of plastic! Over the years, the plastic becomes brittle and breaks off. No longer will the reel be held in place and the machine becomes a noisy (as the reel tries to grip the reel table) heap of junk.
The machine actually was fully functional in all ways but this reel table problem made it pretty unsatisfactory to use and replacement reel tables are like "hens teeth" - it just wasn't worth the effort (for me anyway) to try and source a reel table.
But that said, they are a fun machine to record and playback those mysterious 1/4" tapes that might be lurking in the back cupboard or simply restore a machine for your "technology museum"
Yes, I salvage EVERYTHING from my sacrificial machines! Now you may wonder "what's so special about these pots?" - it's not the pots but the quite unusual fluted shaft that is the reason for keeping and offering these.
National Tape Recorder/Player SPARE PARTS

These items are all related to the dismantling of this machine from National/Panasonic although I wouldn't be surprised if these same components were used across a number of models from National
Suits the Model: RS-760S (this part may possibly suit other National/Panasonic machines)
Made in Japan
Late 1960's - one of the early semiconductor based machines
CONDITION:
Cosmetically all items are in very good - excellent condition, solder tags for each end of the resistance track and the wiper are clean
Each pot (open frame) has had switch cleaner applied and measured by multimeter to ensure the rear switches are ok (where applicable) and that there are no "flat spots" during the wiper travel.
Nut & metal washer included with each pot.
These components (as pictured) have now been sealed within plastic and will be supplied this way.
