Can you replace 5881 with 6L6?
You’re fine to swap out 5881s and replace them with 6L6GCs – that’s an upgrade in valve power rating and plate voltage. I’d be careful putting 5881 in an amp designed for 6L6GC as you are downgrading the valve – putting in a weaker component if you like.
What’s the difference between EL34 and 6L6?
6L6 Tubes – FAQ & Buyer’s Guide! If you think about the classic EL341 guitar tone, an EL34 guitar tone is a particularly British guitar tone. The other main type of output tube is a 6L6. 6L6’s are much less scooped from an EQ point of view. They have a much more flat frequency response.
What are 5881 valves?
5881 tubes (5881 valves) are actually very similar to the 6L6 valve but lower power (23W -v- 30W) and in a more squat tube. They were introduced in 1954. Any amplifier which uses a 6L6 can have a 5881 valve instead but you will need to rebias.
Are all 6L6 tubes the same?
For the most part, 6L6 tubes are interchangeable. The 6L6 along with the G, GA and GB are all rated to the same 19 watt plate dissipation with 360 plate volts.
Is 7025 the same as 12AX7?
The ECC83 (12AX7) Valve The answer is simple. In ‘theory’ you’ll get a bit lower noise and lower hum with a 7025. Otherwise, they are identical.
Can you swap EL34 for 6L6?
You do have to change the resistors. EL34 is way different for bias voltage than 6L6. 6L6 is going to be about -54VDC.
Why are Matchless amps so expensive?
One of the reasons why so called boutique amps are so expensive is that most of them try to use the same types of high quality transformers, caps, tubes, etc. which are getting harder to find and/or more expensive to have made.
Can EL34 replace EL84?
You probably want the natural breakup of the tubes to distort your sound and give you that warm crunch that made you want to play the guitar in the first place. And EL34 and EL84 tubes just enhance natural amp distortion so nicely and drive the amp so well.
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.
What amps use 6L6 tubes?
In guitar amps, the 6L6 was most often used in high-powered amps such as the Fender Twin Reverb, Fender Dual Showman and others that deliver loud, glassy clean tones. The first Marshall amps, JTM-45 head and Bluesbreaker combo, also used 6L6 power tubes.
Is 6L6 a power tube?
6L6 is the designator for a beam power tube introduced by Radio Corporation of America in April 1936 and marketed for application as a power amplifier for audio frequencies. The 6L6 was the first successful beam power tube marketed.
Can a 6L6 replace 6v6?
6L6s generally offer a bolder, tighter feel with a smoother midrange and glassier top, whereas a 6V6 tends to have a little more midrange bite and spongier lows. This means that swapping 6L6s into your 6V6-powered amp would, therefore, require twice the amount of juice from your power transformer.
How long do 6L6 tubes last?
Power tubes can last years in a light-playing situation while lasting only 6 months in heavy playing conditions. It is also dependent on how loud you play and for how long. Also if you don’t correctly match up the impedances, this will put strain on the power tubes and wear them down much faster.
What is the difference between 12AX7 and 12AX7A?
These are not military tubes and are not NOS tubes at all. Also, as tube manufacturing became refined, the 12AX7A became much quieter. So much in fact that a lot of 12AX7A’s were labeled 7025’s (a very quiet version of the 12AX7). So the bottom line is that you can use either of these tubes in your Marshall amp.
What is the difference between 12AX7 and 12AT7?
The biggest difference between these power tubes is the amount of gain they will provide. The 12AX7 has a gain factor of 100, while the 12AT7 has 60. The lower gain of the 12AT7 and 12AU7 also allows them to have a higher headroom, which can provide a warmer and cleaner sound.
What 12AX7 tube is best?

What amps use EL34 tubes?
Common amps with EL34 tubes are: Marshall 1959 “Plexi” Marshall JCM 800. Orange Rockerverb. Hiwatt.
What tubes are compatible with EL34?
EL34, 6CA7 and KT77 are all drop-in replacement of each other. You can use 6CA7 or KT77 in place of EL34. Electrically, they are the same.
Are power tubes interchangeable?
Others are simply fixed—i.e., not adjustable. With a fixed-bias amp, it’s a good idea to check the bias whenever you change power tubes. Even tubes of the same type can run a little hotter (i.e., with more plate current) or cooler (with less plate current) in the same amp—even if they’re the same brand.
Who owns Matchless amps?
Rick Perrotta Type Private Founder Rick Perrotta Headquarters Los Angeles, California , United States Key people Mark Sampson, Steve Goodale and Chris Perrotta Products Amplifiers.
Are victory amps Handwired?
Victory Amps is born! Everything was and is hand wired and assembled in the U.K.
Why are Fender amps so expensive?
Sure, the actual bare bones parts are not that expensive, but guitar amps do actually take a lot of specialized parts like tubes and transformers, that arent really used anywhere else, which makes them more expensive.
