Tube el34 amplifier
Nicely built, nice-sounding tube amp. I read a bunch of mixed reviews, but after owning for a few weeks, I'm very pleased. Powers my JBL 8" 3-way monitors just fine, though I wish there was a little more headroom. The sound is excellent.

EL34 Tube Amplifier
We developed our first EL34 stereo integrated delivering 35W class AB power in — it was a very popular product and we decided to make a MonoBlock version of the design — So we developed a new chassis for the MonoBlocks and added a tube rectified power supply with dual 5u4g tubes! Each channel having a decicated power supply with huge mains and choke! Lets start with the power supply — a Massive mains transformer the T which supplies all the current to the power supply and the circuits!
A huge Choke W in combination with the Mains delivers the AC to the Power SUpply Board — this board consists of two very high quality Mundorf MLytic power supply caps — a uf 4 pole cap and a 30U film cap at the input of the rectifier tube! The Power SUpply also consists of dual 5u4G rectifier tubes in order to supply more than enough current for sudden demands by the audio circuit!
The transformer pulls 6A continuously out of the wall to supply each block and thus size matters! Our PCBs are expertly designed with all signal and chassis grounding implemented with Cathode and HT test points guaranteeing a perfectly working amplifier even for a beginner builder.

LittleZoe EL34 tube amplifier. LittleZoe is a concept high-end amplifier. Its innovative chassis architecture eliminates any noise that affects the tubes and therefore promotes the rendering of dynamic and vivid sound. With an outstanding performance and an elegance that goes beyond modernity, LittleZoe becomes a new reference in tube amplifiers design.
Amplitudes: The Mesa Boogie Blog
Together with Stereo Exchange. This is great vintage tube amp from CJ. This example received a factory film capacitor upgrade to the power supply section. No tube cover is included but we feel it looks way better without it. Please note there's some damage on the output terminal blocks, but they're completely usable and function correctly. The input voltage amplifier included a cathode follower to provide low impedance drive to the inverter stage, to which it was direct coupled, eliminating one capacitor from the signal path. Separate discrete dc voltage regulators supplied dc voltage to the input amplifier and the phase inverter. The SkyFi Testing Process for Tube Amplifiers: We start with a visual inspection of all internal components to make sure there are no signs of stress or aging.

EL34 Baby Huey Amplifier. I must tell you that I am not in professional amplifier business, this is just a time consuming hobby for me and, as you will see, English is not my first language and I have sometimes difficulties to explain things correctly, sorry for that but at least you will understand easily schematics, pictures, B. As I was interested by the shunt feedback concept that I didn't know I wanted to test it and decided to build the simplest version with two PCL86 tubes. This amplifier was very good and I was very satisfied by the MOSFET driver stage, but I was also a little bit frustrated by the limitation in power, about 12 W, and the fact that I could not use different power tubes

Favorite Option Silver - Standard Black - Standard. The speakers can be pushed well with bookshelves or floor boxes with a sensitivity of 88 or higher at around W. It is enough for families to appreciate vocal and string music. If you like symphonic music with low frequency and great dynamics, or if the speaker power is larger and the sensitivity is lower, you can choose our more powerful KT88 tube amplifier. The fever configuration uses the ALPS exponential potentiometer for audio, which is different from the ordinary potentiometer.

Electrically, they are the same. Now, with that out of the way, there is a fair amount of difference in how these tubes sound. Mullard UK designed the EL34 tube in the s. The venerable EL34 tube produces clean, smooth output. EL34 handled lots of power in a thin glass tube. The smaller size and high power made the EL34 tube very popular in audio and guitar tube amps. EL34 tube has a fairly unique sound. In guitar amps, EL34 is all about mids and upper-mids.
20W Power Tube Amplifier with EL34
The EL34 is a thermionic vacuum tube of the power pentode type, first made in It has an international octal base indicated by the '3' in the part number and is found mainly in the final output stages of audio amplification circuits; it was also designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters. In common with all 'E' prefix tubes, using the Mullard—Philips tube designation , the EL34 has a heater voltage of 6. According to the data sheets found in old vacuum tube reference manuals, a pair of EL34s with V plate voltage can produce 90 watts output in class AB1 in push—pull configuration.

The following diagram is the circuit diagram of 20W power amplifier which build based tube component EL EL34 is very famous tube and great for power tube amplifier. The circuit above is complete circuit contains tube amplifier circuit diagram and power supply circuit diagram. To make the stereo channel amplifier, build the similar amplifier circuit only and connect to the power supply using parallel connection with another same amplifier. The tube EL34 is a thermionic valve or vacuum tube of the power pentode type. The Russian analog is 6P27S Cyrillic: 6? The tube EL34 was widely used in higher-powered audio amplifiers of the s and s, such as the very popular Dynaco Stereo 70 and the Leak TL25 mono and Stereo 60, and is also widely used in high-end guitar amplifiers because it is characterized by greater distortion considered desirable in this application at lower power than other octal tubes[citation needed] such as 6L6, KT88 or
