A little audio connoisseur’s favourite!

An integrated audio stereo valve amplifier DIY kit has been prepared based on a trialed and tested design. Constructed using single ended topology, this stereo valve amplifier produces around 3 Watts of pure valve audio output power – perfect for small to medium sized rooms.

Only using two 6BM8 (also known as ECL82) triode / pentode valves (one for each channel) this amplifier delivers a high grade audio across the audio bandwidth with a great soundstage and clarity. Each channel contains two amplification stages performed by the 6BM8/ECL82 valves.

It is only available as a DIY kit that needs to be assembled.

Please note that this kit does not include enclosure. You will have to  choose one here.

How Does It Sound?

Listeners of the system have described the sound produced by the amplifier as high-clarity and very detailed. Paired with a good quality 6BM8/ECL82 valves, this valve amplifier should satisfy anyone who demands a classique valve signatured sound.

There has to be some reasons behind the existence of the “cult of single ended valve amplifiers”. Could it be due to the way audio signal gets amplified in the single ended topology? Unlike the push-pull topology, where the signal is divided into two separate halves (positive and negative halves), there is no risk of crossover distortion of the signal.

There is just something magical about the audio churned by the single ended machine. It sounds so effortless and natural.

If you have any question about this, please get in touch.

The Kit

This valve amplifier DIY kit (buyer needs to assemble) enables you to build a fully working high quality valve amplifier with relative ease.

All components have been sourced with quality vs cost in mind and have been thoroughly tested by us.

Remember that you have the assembly manual to work with. The manual contains high resolution images and detail instructions on setting up the kit.

Variations of the Kit:

  1. Basic Kit – contains all PCBs, transformers, switch, potentiometer (knob not included), connectors, fixings (screws, nuts, bolts, spacers) – you supply the valves and enclosure
  2. Basic Kit + 2 valves

Don’t forget that you can also purchase a suitable enclosure with the aluminium top plate for this kit.

If you prefer to buy only the amplifier PCB and its component (without transformers etc) then have a look HERE.

The Enclosure

An optional enclosure can be selected to be part of this kit. You can read more about the enclosure here. We highly encourage you to purchase an enclosure as it comes with a pre-drilled mounting plate. The mounting plate will not only make assembling the kit pretty straight forward, it also enables you to use the default positioning of the components and parts.
