Title: Lot of 10 used type 24 vacuum tubes + bonus
Item: [24-5] $5.00
Here are 10 used type 24 tubes from various manufacturers
including RCA/Cunningham, National Union, Tung-Sol and Raytheon
Some have a loose cap, are leaky or have weak emissions.
Repair them and you can have some nice tubes for a real bargin.
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.
