HISTORY:
Working through yet more reel to reel related accessories and media plus some PHILIPS reel to reel tape machines, models N4504 & N4512
This is the small leaf switch associated with the supply side tape tension lever. If you have a "sloppy tape tension issue", this MAY be the cause of your problems.
Not a bad machine from Philips, 3 motors, separate Read and Write heads in addition to the Erase head, 3 run speeds but not all that impressed with the extensive use of plastic for the case, albeit high impact very strong plastic! This makes for a pretty lightweight machine compared to the Otari 5050's and Studer B67's I have lugged around in the past!
There was actually very little "wrong" with the machines I am "parting out" but I felt they were more useful as "organ donors" to bring other machines back to life (or improve their functioning) so they are currently being "operated on" to extract useful components.
While the switch is physically strong and unlikely to fail, the leaf contacts are open to the world and do (over time) have contact oxidising issues - the switches I am offering have been extensively "cleaned up" and ready to instal and provide reliable operation of the automatic tape tensioning system designed by Philips. This switch (SK13) is an integral part of the tape tension system, in association with TS2, TS3 and other components - see the Service Manual page 11
I am very much "into" sustainability and 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.
