Amplifier power tubes comparison

The functional difference between the 6L6 and the 6V6 is that the 6L6 is a much higher power tube about 25w , which means in practice it has a punchier tone with tighter bass and glassy highs. The 10w 6V6 on the other hand is more mellow with a creamier midrange-rich tone, sounding closer to an E34 — all tube tone with less volume, similar to an EL The 6v6 is only designed for a max signal power of 5 watts output while the 6L6 can handle Sonically, the 6V6 sounds warm but gritty — it does a gnarly overdrive without any strident highs.

What’s the Difference Between Gain and Volume?


What is the difference between "rectifier tubes" and "power tubes". May you should read about vacuum tubes a little. Have a Happy New Year. What is the difference between "rectifier tube EZ81 " and " power tube EL Find More Posts by DF Sorry my ignorance all tube rectifiers don't have grids, right? Basically a Rectifier Tube will have no control grids. It will conduct fully in one direction and not in the other. A Power Tube is just a high power amplifying valve. This will have one or more control grids which control the flow of current through the valve.

Thanks for the info, other question: one tube amplifier can be used as tube rectifier? Current can flow only in one dircetion , there are single wave rectifiers 1 anode 1 cathode and full wave retifier 2 anode 1 cathode , again some are direct rectifiers and heather is the cathode , indirect rectifiers have separate cathode and heaters.

EZ 81 is a indirect full wave rectifier. What you need to use this tube is a power transformer with a separate heater supply wiring for the EZ81 , don't use common wirng for rectifier and other tubes heaters. On cathode you'll get positive voltage.. Be careful with the smoothing capacitor value , silicon rectifier accept large capacitors , vacuum rectifiers need a capacitor with value in accordance with datasheet , for the EZ81 is about 50uF.

If you exceed the value stated in the datasheet the tubes may arcing Power Tube function is give power to the speaker. Preamp tube amplify audio signal increasing voltage , power tubes amplify most in current. Due tu the high impedance output of tubes also power tubes you need a transformer to couple plate impedance to speaker impedance. Quality of transformer is one of the most important factor on the global quality of a tube amplifier. Since your would be a guitar amp , you don't need an high quality output transformer , an HiFi transformer is the worst thing you can put in a guitar amp.

Apologies for my bad english Originally Posted by merlin el mago. In fact power tubes can and have been used as rectifiers. In that case the grid gets tied to the plate. Wether this is sensible is another question Western Electric did this in some of their amps. I think the idea behind this was to reuse the s from the amplifier sockets for some more time as rectifiers.

They also did this in a D amp. However there is no published data about the diode characteristics of triodes you need to characterize them yourself for rectifier use. However I would not recommed this for a beginner Thomas. Find More Posts by Vinylsavor. BB code is On. Smilies are On. Forum Rules. All times are GMT. The time now is PM.

The best guitar amps to buy in 2021: 15 best tube amplifiers

They have a power outlet of up to 55 watts and a maximum resistance rating of 5. The best 6L6 tubes are renowned among musicians for electronic recording and performance since their introduction way back in 1. Although they have been replicated and revised throughout their history 6L6 2 tubes are still the top choice for guitarists specializing in rock, blues, and jazz. These tubes are used in amplifiers to convert the incoming sound into a steady and full sound in the amplification process. Although new amplifiers get phased in, due to their power usage, musicians will take many years to stop utilizing 6L6 tubes in their equipment for the quality of sound.

Vacuum Tubes and Transistors Compared


However, guitar amps typically feature two different tube-powered amplifier sections: the aforementioned preamp, and the power amp. The power amp section of your guitar amp is what actually drives volume into a speaker , which requires a significantly higher amount of amplification power than the tubes used in the preamp. As such, guitar amps have a wide variety of even more tubes that are used to power the amp, each with their own unique tone-shaping characteristics. In general, EL34 and 6L6 tubes are typically used in higher wattage applications , usually amps that are over 50 watts. The EL34 tube is among one of the most used tubes in any guitar amp. They are known for their very high headroom and high output wattage, with a pair easily being able to push out around 50 watts in a typical Class AB amp configuration. It is important to note that amplifier designs that employ EL34 tubes are typically large and tend to sound best when they are pushed into loud volumes, so these amps might not be the best for your studio apartment! Common amps with EL34 tubes are:.

Similarly, guitarists and bassists use gain all the time, yet many would be hard-pressed to tell you clearly and correctly what gain is, exactly, and how it relates to volume. Granted, you needn't be able to define "gain" in order to use it-you just know you turn that knob and something cool happens to your sound; usually something to do with distortion. That's perfectly OK, but if you're new to amps - more specifically, new to buying an amp - it might help to know what gain is and how it's related to volume, as the two are closely related. Some amp basics are in order first.

The problem is, not many of us have the luxury to a tube tester, leaving us in the dark with our amps diagnosis and treatment. Even if we did, a tube tester is not capable of painting a clear picture with the problem with our delicate tube amps.

Valve types explained


Solid-state technology all but obliterated the vacuum tube market in the early s. So why are tubes still popular with audiophiles and musicians? I thought it would be fun to contrast and compare the tubes vs. But if solid-state is so terrific why haven't tubes become extinct in the half century since transistors came onto the scene? Maybe, just maybe, because tubes sound better?

This article covers some of the questions and provides some info on reasons for changing preamp tubes. The most common preamp tube for tube guitar amplifiers is the 12AX7. Unfortunately, depending on the amplifier and application there will be several good options but nothing will be perfect every time. We test preamp tubes before we install them so we have some idea of what kind of result to expect. There are an infinite number of factors power supply capacitors, transformers, pick attack that contribute to the sound of an amplifier and changing the preamp tubes is one of them. Here are a couple reasons to change things up:.

Today, it is by far the most common preamp tube used for electric guitar amplification and there is an almost overwhelming supply of current production options.

Do different tubes really change the tonality of an amp...

Guitar Amps. Welcome to my review of the 15 best small tube amps to play with valve flavor everywhere! If you are looking for a small tube amp you are in the right place. Click here to skip the quick overview and jump right to the in-depth reviews.

In overdrive, it offers a tight and focused bite with crisp, bright and well-defined articulation. We take great pride in our packaging and take every precaution in ensuring that your tubes reach you in perfect condition. All tubes are shipped in their factory packaging and for added safety a secure, void filled carton. We are so confident that your tubes will reach you intact that we promise to replace any damaged tubes or give a full refund. Comparing a worn out tube that is out of speck to a new tube is kind of unfair.

We all know vacuum tubes are different. If you change type or brand you get different characteristics and different audio quality.

Some guitarists religiously replace the tubes in their amps every two years; others never do so, or not until the amp takes a vow of silence. Playing guitar at home has never been as convenient, rewarding and motivating as it is today. Now, though, thanks to innovative technology we can do this even at low volumes in the comfort of our cribs. Some modern-day tube amps deliver stunning sound at low wattages. This all adds up to countless hours of bliss for guitarists.

This is done so the tubes can work together in your amp giving you optimal sound quality and tube longevity. Matched tubes also receive extra quality checks to reduce the possibility of getting a faulty power tube that may have slipped by the manufacturer. Let's look at some of the basics of how tubes work to have a better understanding of the benefits of using matched tubes versus unmatched power tubes in a guitar amp.
