What is a vacuum tube radio?
A vacuum tube, also called a valve in British English, is an electronic device used in many older model radios, television sets, and amplifiers to control electric current flow. The cathode is heated, as in a light bulb, so it will emit electrons. The anode is the part that accepts the emitted electrons.
Can you replace EL34 with KT88?
EL34 and KT88 share the same pinout and are interchangeable in some circuits.

When did they stop making tube radios?
Which means that whether your antique radio is a cathedral or All radios produced during the first half of the 20th century were tube radios, since transistors were not invented until 1947 and did not start to replace tubes in radios until 1954.
Why do vacuum tubes sound better?
We use tubes simply because they make the music we create sound better: smoother, warmer and cleaner. Ditto for guitar amplifiers used in creating music. The ways that tubes distort when pushed to the edge are much more musical than the artificial sounds that come from transistor amplifiers when overdriven.
What brand of tubes does Marshall use?
Usually all the tubes therein are 12AX7/ECC83 types. The model 2001 uses two 12AT7s and three 12AX7s. Marshall tube amps usually have solid-state rectifiers. Only a few early models, such as the original JTM45, used a tube rectifier.
Is 12AX7 the same as ECC83?
The 12AX7 Valve (or 12AX7 vacuum Tube) is a small preamplifier valve which is identical to the ECC83 – same valve, just a different name. It has two identical triodes both of which have a high voltage gain. In fact, it is one of the few small-signal vacuum tubes in continuous production since it was introduced.
How do I know if my amp tubes are bad?
Crackling, squeals and feedback, excessive noise and muddiness or low output are all evidence of tube problems. Power tubes. The two main symptoms of a power tube problem are a blown fuse or a tube that begins to glow cherry red. Either are typically indicative of a power tube failure.
How long do vacuum tubes last?
Tubes don’t just “quit” suddenly. They lose their drive capability gradually with use. Small signal tubes like a 12AX7 or 6922 will work well on average for about 10,000 hours. If you leave your equipment on 24 hours a day, well you do the math: There are 8,760 hours in a year.
What replaced the vacuum tube?
