Description

General Electric Mil-Spec P7761569-6, 20-84 pF 4000V Single Section Air Variable Capacitor

 This capacitor is very heavy duty and weighs nearly 1 1/2 pounds. It has ceramic stand off blocks attached and included.

Key Specifications:
  • Capacitance: Approximately 20 pF minimum to 84 pF maximum (single section; your measurements). Related P7761569-series units (e.g., PT-4, PT-7 variants) are documented in the 16–111 pF range depending on exact suffix/revision.
  • Voltage rating: Approximately 4000–4725 V AC peak (consistent with the GE/military P7761569 family and ~1/16″ plate spacing). Exact rating for the “-6” suffix is not separately published in available references, but the series is high-voltage transmitting-style.
  • Plate spacing: Approximately 1/16″ (supports the high voltage rating).
  • Shaft: 1/4″ diameter round.
  • Dimensions: Length ≈4⅝″, width 2¾″, height 3″ (matches the mid-size members of this military series).
  • Construction: Single-section air dielectric, unenclosed frame typical of GE military surplus variables, ceramic/insulator supports, solder terminals.
These are rugged military-spec units from the General Electric P7761569 family, designed for high-voltage RF applications.
