Tube & Transistor Radios
Count transistors on the badge or look for glowing glass — pre-1963 shirt-pocket transistor radios and any working tube set are collector items; 70s+ plastic AM/FM is parts and copper.
How to spot it
Tube sets: wood or Catalin/Bakelite cases, octal or 7/9-pin miniature tubes, power transformer, Alnico speaker. Catalin cases alone are $200–2,000. Early transistor: Regency TR-1, Sony TR-55/63, Zenith Royal 500 — civil-defense CD marks on the dial date them. Ham/CB gear follows the tube rules with a stronger used market.
Metal content
| Metal | Quantity | Notes |
|---|---|---|
| Copper | 20–40 g/lb (tube sets) | Power and audio transformers, chassis wiring; transistor sets are plastic-light |
| Silver | trace | Silver-mica caps and switch contacts in tube-era chassis |
| Base metal | Alnico speaker magnets | Cobalt-nickel alloy — payable at specialty yards and prized by speaker builders |
At 4 Aug 2026 spot prices that works out to $0.51 per lb of contained metal — Copper 30 g = $0.32, Silver 0.1 g = $0.19. A refiner paying $0.15 per lb returns about 29% of that, which is normal: refining costs money and the buyer takes a margin.
Safe removal
Working temperature: No heat needed — mechanical teardown only
Tube sets: pull tubes first (padded box — they are half the value), then transformers to copper, silver-mica caps to that stream, Alnico speakers whole. Discharge the big can capacitors with a resistor lead before touching the chassis — tube-era electrolytics hold a bite.
Hazards
NEVER short a large capacitor with a screwdriver. It welds the tip, blasts molten metal at your face, and can rupture the can.
NEVER blow on, wipe with bare fingers, or brush away cut optical fibre.
NEVER dry sweep or use compressed air on a scrapping bench. HEPA-vac or wet-wipe only.

Questions
How much gold is in tube & transistor radios?
Copper: 20–40 g/lb (tube sets). Silver: trace. At current spot that is about $0.51 of contained metal per pound.

Is tube & transistor radios worth more working than as scrap?
Working tube radios $40–300, Catalin cases $200–2,000, early transistor sets $50–500, tubes and output transformers as parts, Alnico speakers $10–40 each to builders. Scrap only rusted gutted chassis.
