I have Zenith radio madel l721 how much is it worth?

Answer 1

If the cabinet is crack free, the clear plastic dial face is clear and crack free and the radio plays loud (on both bands) without any noticeable hum, it could be worth $50-$75. Zenith made a lot of these so there not particularly hard to find. repairing often involves replacing capacitors inside the IF cans. This symptom is very common for this vintage of radio. Hope this helps.
