The General Radio 874-VC Variable Capacitor was introduced in Catalog N (1954) and remained available through Catalog Q (1961).
The Type 874-VL is a general-purpose variable capacitor used as a tuning element in resonant line circuits, matching transformers, and baluns at low frequencies. Can be used as a general purpose shielded capacitor at lower frequencies. The 874-VL is very similar to the Types 1602-P3 and 1607-P3 variable capacitors used as low-frequency susceptance standards, all are based on the 1420 series of variable capacitors.
Specifications
- Capacitance Range: 14 to 70 pF at low frequencies; at high frequencies see curves in data sheet
- Capacitance Variation: Linear
- Dial Calibration: 0 to 100 not in capacitance
