What is a 6973 tube?

What is a 6973 tube?

The 6973 is a legendary tube used commonly in Jukeboxes but also some guitar amplifiers. The 6CZ5 is a similar tube and is SOMETIMES a suitable substitute for 6973 but not always. The 6CZ5 has significantly lower plate voltage limits and pin 8 is different. The tall bottle version is said to be most similar to 6973.

Are tube amps worth it 2020?

In many cases, tube amps do not require the amount of maintenance that they have a reputation for. As long as you properly take care of your gear, owning a tube amp is simple and very well worth it for the tone.

Why do tube amps sound better loud?

Because valve/tube amps have an output transformer causes the amp to have a ‘high output impedance’. This is a form of distortion, as the speaker is not following exactly the signal the amplifier is feeding to the speaker. This is the only reason a tube amp ‘can’ sound louder than a elderly transistor amp design.

Why are tube amplifiers so expensive?

Tube amps are expensive because they adopt pre and power tubes as their primary amplification source. Each tube costs roughly $50 and can have up to 4 of them within a single unit. Secondly, these amps have more expensive components, larger cases, and more complex circuitry than solid-state amps.

Why are tube amps so heavy?

Tube amps require a few more components such as voltage transformers (several per tube) that contain heavy magnets. Because of this added weight the chassis that the components are fastened to are made out of steel or other heavy metals for sturdiness as opposed to aluminum like in solid state amps.

Why does my tube amp crackle?

Random Crackling and Pops This typically signifies your amplifier has faulty power tubes. First, try swapping them one by one with a spare tube. If this does not fix it, then the preamp plate and/or cathode resistor need to be checked out (this is probably something to get a professional tech to do).

Can you substitute A 6973 tube for a 6em5?

I think you can use a 6CZ5 tube but you’ll need a small rewire. You should also check the data sheets and compare the two. The problem is basically maximum plate voltage ratings with either the 6CZ5 and 6EM5. The 6973 is a true audio output power tube with higher plate voltage ratings. These others were made more for televison sets or something.

Which is a better power tube 6973 or EL84?

The 6973 is a true audio output power tube with higher plate voltage ratings. These others were made more for televison sets or something. I think if I was rearranging pin-outs somehow I’d be better off converting the amp to use EL84 tubes.

Is the Electro-Harmonix 6973 power tube a rebrand?

Electro-Harmonix 6973 Power Tube Beam power amplifier used in vintage Gretsch and Magnatone amplifiers. This is a real 6973, not a rebrand of a “close” tube. You must be logged in to add items to a project list.

What can I use as a substitute for A 6973?

Go to http://tdsl.duncanamps.com/ and type the numbers of the tubes you want info for. It will have several links for the info as well as substitutions. Electro Harmonix reissued the 6973 at close to half that price.
