Are old vacuum tubes valuable
Radio restorers are always on the lookout for 01A tubes ($10-$15) used in most 1920s radios. These tubes also used the numbers 201A and 301A depending on the manufacturer. Other early tube numbers to watch out for are 45 ($50-$70), 50 ($200+), 245 ($100+), 250 ($250-$350), WD-11 ($50-$135), and WD-12 ($30-$50).
Why are old vacuum tubes better
Modern Tubes Do Not Last
Tone aside, modern vacuum tubes go bad at a much faster rate than do vintage tubes, and that alone is a reason to go vintage. We know this because we often sell to folks who are replacing faulty new tubes.
Why did we stop using vacuum tubes
Vacuum tubes suffered a slow death during the 1950s and '60s thanks to the invention of the transistor—specifically, the ability to mass-produce transistors by chemically engraving, or etching, pieces of silicon. Transistors were smaller, cheaper, and longer lasting.
What replaced vacuum tubes in computers in the 1950s
In the 1950s, the invention of the transistor began to replace the vacuum tube, as vacuum tubes were larger, fragile like a light bulb, and expensive. As computing devices began to get smaller, transistors were more ideal for use because of their smaller size.
