HISTORY:
Working through yet more reel to reel related accessories and media plus some PHILIPS reel to reel tape machines, models N4504 & N4512
This large value electrolytic capacitor is used in either model OR of course the capacitor can be re-purposed into other equipment (usually the power supply section)
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.
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.

Electrolytic Capacitor (Power Supply Filtering)
Type: 3300uF 40V (CE-W 85 Degrees 84-4)
Aluminium cylindrical case, bracket (supplied) fixture.
Solder tags
DIMENSIONS:
30.5mm diameter x 50.5mm height

NO marks or scratching
I have two of these, one with a Black insulating sleeve and the other has a Light Grey insulating sleeve
TESTING:
Being used (although working fine in the R2R machines prior to removal) I tested them both ...
Black: 3523uF ESR: 0.78 Ohm
Light Grey: 3671uF ESR: 0.81 Ohm
I have now packed these capacitors individually into sealed clear plastic packets, awaiting a new owner
