Description

Reliance Die & Stamping, Three Section, 24 to 500 pF 1500 Volt Air Variable Capacitor.

 To Date, I have (3) of these capacitors in stock.

Key Specifications:
  • Brand: Reliance Die & Stamping Co.
  • Model: Unknown (marked with patent date May 5, 1925 and other patents pending)
  • Sections: 3 (three-section / 3-gang)
  • Capacitance: 24 pF minimum to 500 pF maximum per section
  • Plate spacing: Approximately 1/32 in (0.031 in)
  • Estimated voltage rating: ~1500 V peak (standard ARRL Handbook guideline for ~0.030–0.032 in air-gap spacing; practical RF rating for receiving or moderate-power use)
  • Shaft: 1/4 in diameter
  • Dimensions (approx.): Length 3-3/4 in, Width 3-1/4 in, Height 4 in
  • Construction: Classic multi-plate air-dielectric design with aluminum frame, ceramic or porcelain insulators, and three ganged sections on a common shaft. Typical of 1920s–1930s receiver-style tuning capacitors from Reliance Die & Stamping.
Exact original model number and factory voltage data were not located; the voltage rating is derived from the measured plate spacing.
