Title: Lot of 12 Used Type 25Z5 Vacuum Tubes + bonus
Item: [25Z5-1] $6.00


Here is a lot of 12 Used Type 25Z5 Full-Wave High-Vacuum Rectifier Tubes from various manufacturers
including RCA, National Union, Hytron, Champion, Ken-Rad, Tung-Sol, Kadette and Raytheon

Some are leaky, some have weak emissions.
What does "leaky" mean? The designation of leaky means that there is a high resistance
connection between two or more of the tube elements.
Most commonly this is between the cathode and the heater and typically one to ten megohm or higher.
For many applications a leaky tube can still work fine, or may cause a slight "hum" in the
output. The leaky condition prevents us from selling the tube as "good".
That means that you can get a great deal on our less than perfect tubes.

Condition and test results listed below.
Each tube has its own tag showing the condition and test results.
