Here are two used type 32 tubes, five type 34 tubes and two type 36 tubes
from various manufacturers including Tung-Sol, Wards, Sylvania, Silvertone and National Union

Some have a loose base, leaky or 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.

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