As removed from radio receiver equipment
Manufacturer unknown
Known to date from the late 60's - early 70's
Most likely to be of Japanese origin, possibly ALPS
Marked on the side as:
XVC 179
Stamped into one end is:
ISO
5 gang
Component dimensions:
BODY - 63mm depth x 30mm wide x 30mm height
SHAFT - 20mm long x 7mm diameter with no flat spot. Usually a large pulley will be attached to this shaft, tuning being made via a pulley arrangement.
Mounting bolts are included
Capacitance has been measured and the results are below.
COSMETIC CONDITION:
Extremely important is the physical condition of these capacitors.
This component is excellent.
No deforming of the vanes - no bends and absolutely no touching of the vanes during rotation
No corrosion
All aluminium construction using phenolic resin insulation strips for the terminal substrate
TESTING:
This variable capacitor has 5 gangs
Gang 1: 0 - 10pF
Gang 2: 0 - 330pF
Gang 3: 0 - 10pF
Gang 4: 0 - 330pF
Gang 5: 0 - 10pF
These are actual test results and it was confirmed during testing that there is no shorting of plates/vanes during rotation on any gang.
This appears to have been designed for a receiver front-end tuned circuit, the larger capacitances for MF and the smaller capacitances for VHF i.e domestic receiver however this variable capacitor could be used in many RF tuned circuit projects.
