We are passionate about vintage vacuum tube audio.

What We Do

Mars Tube Audio is a producer of affordable high-end tube audio equipment, as completed products or DIY kits.

All our completed products are assembled and hand-wired at our workshop in Paarl, Western Cape. 

We offer guided workshops for DIY projects.

We also service, repair and renovate tube audio equipment.

Single Ended Triode Amplifiers

A good SET amplifier combined with a single full range driver with no crossover or a simple two-way using minimal crossover parts on the tweeter only, has a purity and depth that you simply don’t find in more conventional systems.

Single Ended Ultra Linear

If you want more power than single ended triodes, and you do not want push-pull, then you listen to single ended tetrodes. Tetrodes have a more commanding bass control and higher sensitivity than triodes. This bring out the clarity and detail in music. 

Push-pull amplifiers

Push-pull amplifiers are the workhorse of hifi. If you have regular hifi loudspeakers, this is the amp you are looking for. More bass control and effortless sound.

What our customers think

After a bit of a learning curve and over a few months I got my Mars 5E3 Tweed Guitar Amp kit completed. Instructions were straight-forward enough for even a first-timer to complete. What an experience! And what a sound! It is my main amp now. I can't wait to do another kit from Karel and MarsAmps!
