TRIO JR‑500S Communication Receiver - Vintage Valve/Transistor Hybrid - Crystal‑Stabilised

A well‑kept TRIO JR‑500S communication receiver from my personal collection. The unit powers on and operates well.

Condition

• Fully working in normal use
• All controls, switches, and tuning functions operate smoothly
• Valves are original and still test strong, giving excellent sensitivity and audio
• Cosmetic condition appropriate for its age (see photos)

Technical Highlights

• Classic valve‑based RF and IF stages, providing warm, clean reception
• Transistor‑based local oscillator (LO) for excellent frequency stability
• LO uses multiple crystal‑controlled stages, resulting in exceptionally low drift
• Crystal‑controlled BFO, ensuring stable SSB and CW operation
• Combined architecture delivers near‑zero drift, even during long listening sessions
• A superb example of TRIO/Kenwood’s early hybrid engineering
