I was repairing a Tivoli radio that had a problem in the power supply. It has a Zener diode I was not sure the diode was the problem and I couldn't read the number on it to order one. I didn't want to un solder it to find the number. For a little more money than buying just the exact diode and having it shipped I bought this comprehensive selection on Prime. The Zener diode was not the problem and I didn't use one out of the kit so I can't comment on them. Now I have a good selection of Zener diodes and are prepared for any situation.
