Full Five: 5-watt push-pull ECC99 tube outputfor a quad of triode fidelity and power. This amp is for anybody who wants low wattage with lots of amazing headroom and high volume capability, very different from low-wattage single-ended amps. It uses a Billy Rocker preamp and phase inverter. Available in 10” or 12” speaker combo as well as conveniently-sized head (15'W x 7'T x 7.5'D) capable of driving just about any speaker cabinet. $1,100 ($950 head).
SE-Five: 5-watt single-ended EL84 and 6V6 tube outputwith 5Y3 and 12AX7 tubes. Lush tones at low volumes. Warm and rich, perfectly suited for the studio. Go from either 6V6 and EL84 output at the flip of the switch. This model is equipped with a 10' Weber Feromax speaker; however, other speaker types and sizes are available. $1,249 ($999 head).
Standard 5-watt model without switchable output tube $1,149.
SE-Ten: 10-watt single-ended 6L6/5881 and 6CA7/EL34 tube output with 5AR4 and 12AX7 tubes. This model is the big brother of the SE-FIVE. It comes with 12' Weber Feromax speaker (other types and sizes also available). $1,349.
Billy Rocker: 16-watt cathode-biased 6V6 or EL84 output tubes operating in class A push-pull with 5Y3, 12AY7, and 12AX7/7025 tubes. Reminiscent of vintage tweed-era warmth but with unique tonal qualities. A very popular choice for the studio or small club (or any venue when using a microphone). This amp will actually put out more than 16 watts when over-driven. Also available with reverb. $1,249 for 10' speaker model; $1,299 for 12' speaker model.
Hall Rocker: 20-watt fixed-biased 6V6 output tubes with reverb with 5R4, 5751, 7025, and two 12AT7 tubes. Decent headroom yet plenty of crunch when you need it. Very dynamic with dark reverb overtones. $1,439.
Billy Rocker II: 40-watt cathode-biased 6L6 output tubes with 5AR4, 12AY7, and 12AX7/7025 tubes. Big sibling of the 16-watt 6V6. All the rich, warm tones with twice the volume. For more gain the 12AY7 can be replaced with a 5751 or 12AX7 without any modifications needed. Also available with reverb and or tremolo (Tremotron). $1,399.

El84 Single Ended Guitar Amp Layout

Feb 25, 2017 An amp project especially for first-time builders of a single-ended design using the 6BQ5/EL84 tube in triode mode. Sovtek EL84 - The Sovtek EL84 has been a staple for Fender, Boogie, Crate, Peavey and other manufacturers of tube amps using the ’84. This tube really is a good value. It is predictable, reliable and affordable. You can get good EL84 tone at a reasonable price. This is a pretty unique amplifier. First off it is of course Class A as all single ended amplifiers are. But this amplifier is direct coupled between the driver (6072A) and the EL84 output tube so it can go Class A2 and therefore deliver more power than a standard single ended EL84 amplifier. A2 indicates that the grid can be pushed positive.

2W Tube Guitar Amplifier, 12AX7 & 12L8GT Single Ended

I built a Decware stereo single ended sv83 amp. Citrix receiver 12.7.0. You can use EL-84's if you like but I prefer the russian 6p15. You can get a circuit board from them or you can build it point to point. I built mine without the board. I have owned a bunch of single ended 6v6 and EL84 amps (and have tried the Yellow Jacket EL84 converter in all of my 6V6 stuff). In a single ended set-up, the 6V6 is dark, smooth and can get ragged/wooly when pushed to the max. The EL84 stays strong in the mids and highs to the point of harshness when pushed.

This is a low power Guitar tube amp suitable for practicing, recording or miking through a PA system. The preamp circuit and features are similar to those on a Fender Tweed era Princeton: Single Channel, Volume and Tone knobs.

The 12L8GT output tube used is pseudo exotic, but full of sweet tone. It is a dual pentode in a single bottle with an octal base. In this circuit the two sections work in parallel single ended. Gibson did something similar in a version of their Gibsonette, except they used 6V6GT.

I built mine as a head, but it could easily be built as a combo. 2W can be surprisingly loud. This is not a 'bedroom amp' unless you equip your speaker with an L-pad or similar circuit. Use link below for the PDF schematic.

5W Tube Guitar Amplifier, 12AX7 & EL84 Single Ended

Almost identical circuit to the 2W amp, except output tube is a single ended EL84 (6BQ5). This is a fairly typical design that resembles entry level amps from the 1960's. Loads of tone.
