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

- Combined architecture delivers near‑zero drift, even during long listening sessions
- A superb example of TRIO/Kenwood’s early hybrid engineering
