Common amps with EL34 tubes are:
- Marshall 1959 “Plexi”
- Marshall JCM 800.
- Orange Rockerverb.
- Hiwatt.
Also question is, are 12AX7 and 12AT7 interchangeable?
You can interchange a 12AX7 with 12AT7, 12AU7, 12AY7 or 5751 as they are all the same pin structure, however they will each give you a different result in your amp. Each of these tubes has a different gain factor, which means some will give higher gain and others lower gain.
Beside this, are 6L6 and 5881 tubes the same? You can immediately notice that the 6L6 and 5881 are in the same family of valves. They are part of the general evolutionary process for this particular valve. So they are similar, but not identical tubes. In other words, there are no 6L6 tubes which are identical to the 5881 tube.
Secondly, can I use all EL34 tubes in my amp?
It’s still possible to find every version of these tubes, and they are all interchangeable. The original EL34 tubes will bring out the midrange frequencies, and they will help give you that classic Marshall tone.
Can I use EL34 instead of 6L6?
You do have to change the resistors. EL34 is way different for bias voltage than 6L6. 6L6 is going to be about -54VDC.
Do Orange amps use tubes?
A reprisal of THAT sound
Times have moved on since the early OR series amplifiers with the modern equivalent, the Orange OR15 features EL84 power tubes.
How do you bias a EL34 tube?
Some amplifiers such as cathode biased amps are generally good to go without any adjustments but many amplifiers have a fixed bias. These amps require a bias adjustment for the tubes to operate properly.
| Output Tube | EL34 |
|---|---|
| Recommended bias point for Class A amps | 90% |
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.
What amps use EL84 tubes?
EL84 tubes can be found on Vox AC30s and AC15s along with some smaller Marshall amps such as the DSL combo series. When pushed, EL84 amps can have plenty of bite, although some designs may feel a bit too harsh or stiff for certain players.
What amps use KT88 tubes?
KT88 tubes are currently made by New Sensor, JJ and Shuguang. Marshall used them in their 200 watt Marshall Major amps. KT88’s were also used in Hiwatt Custom 200 and 400 bass amps. They can be used as a substitute for 6550 or even EL34 tubes, if you’re looking for tighter, cleaner tone with less distortion.
What is EL34 amp?
The EL34 is found in many British guitar amps and is associated with the “British tone” (Vox, Marshall, Hiwatt, Orange) as compared to the 6L6 which is generally associated with the “American tone” (Fender/Mesa Boogie; the earlier classic Marshall “Plexi” amps used the KT66, a beam tetrode similar to the 6L6, as well).
What tubes can replace EL34?
Other common substitutes for EL34 vacuum tubes are 6CA7 and KT77 tubes. Although not identical, they are close enough to be considered direct substitutes in almost any instance. The EL34, 6CA7 and KT77 also have similar pin outs.
What’s the difference between 6L6 and EL34?
If you think about the classic EL343 guitar tone, an EL34 guitar tone is a particularly British guitar tone. It has a slight mid-range scoop, which to European ears is quite a pleasing sound. The other main type of output tube is a 6L6. 6L6’s are much less scooped from an EQ point of view.
What’s the difference between EL34 and EL34B?
I think you will find EL34 is the original copyright title from Mullard and other manufacturers back in the day when production was good and EL34B is the new build version. EL34s as NOS cost an arm and a leg and EL34Bs from China/Eastern Block, are relatively cheap. They are basically similar in performance.
Whats the difference between EL34 and KT77?
The original EL34 tubes will bring out the midrange frequencies, and they will help give you that classic Marshall tone. The 6CA7 and the KT77 tubes have a much deeper and more open sound with a cleaner high end. The re-issue of these tubes makes it possible to try them out and find the sound that is right for you.
