AMT Tubecake TC-3 – 3W Power Amplifier (100% analog)

Features overview

These are amazing, small, compact units that will find a spot directly on your pedal board. Also, your dream of running stereo heads can now be a reality at a fraction of the cost. Many guitarist are running dual Tube Cakes as their main rig.

The most prominent features which make the sound of tube amplifiers so popular, have been thoroughly implemented into the design of the Tube Cake series by the engineers here at AMT.

TC-3 Tube Cake 3 Watt version is perfect for those players looking for a more powerful amplifier than the TC-1. Cleaner drive at lower volumes. A favorite with our hard rock and metal guys! Works as a perfect combination all of the AMT preamps.

Tech talk

While creating a lightweight and compact TUBE CAKE TC-3 amplifier, AMT focused primarily on implementing the basic features of a tube amp using semiconductor component base but without the drawbacks such as high cost, large size and weight, and the need for periodic tube replacement (up to 2 – times a year).

The most prominent features, which make the sound of tube amplifiers so peculiar have been thoroughly implemented by the engineers of the company in the TUBE CAKE TC-3.

Output impedance of the TUBE CAKE TC-3 is comparable with the load. Such an output resistance in combination with the impedance of a frequency-dependent guitar speaker, shapes the “correct” guitar amplifier frequency response.
TUBE CAKE TC-3 has a smooth transition from the linear mode to chopping with domination of low serial number harmonics in the spectrum.
Despite its relatively low power TUBE CAKE TC-3 has a large dynamic range, since the chopping, like in fully powered tube amps, is not so noticeable.

Such an amplifier can be used in cases where great volume is not necessary, but you need a specific extra load, peculiar to vacuum tube amplifier: for home practicing, guitar recording at home and playing in small clubs.

TUBE CAKE TC-3 can fulfill this task with nice sound loading and keeping it natural.


VOLUME controls the overall db sound level output of the amplifier.
PRESENCE adjusts the amount of “clarity” or “attack” of the amplifier.
DEPTH adjusts the amount of low frequency resonance of the amplifier.


18V DC voltage required at 500mA power consumption.
Cabinet output rating at 8 Ohm.
3 Watts of amplification power


Connecting TC-3 to Audio interface

Q: I would like to record the output signal from the tc-3 without miking an amp. Can I connect the output of the tc-3 to my audio interface directly without running the risk to damage my audio interface device? My audio interface has inputs designed for conventional dynamic microphones and also a Hi-Z-input for a guitar.

A: You can’t connect TC-3 to an audio interface, it will burn it! If you want to record guitar without micing cab – use preamp output to an audio interface and then use software cab emulation. And remember that TC_3 is a power amp, not a preamp, so you can’t connect it to any audio interface.

Connecting TC-1/3 or Stonehead to 16Ohms cab.

Q: Hello, I own a Tube Cake Tc-3 and a 16 ohms stereo cab. Can I plug it into the 16 ohms input to use the two speakers or is it safer to run only one speaker at 8 ohms.

A: You can plug Stonehead, TC-1 or TC-3 to 16 Ohms cabinets, such connection gives more bass response. If you don’t like the sound you get, then run only one speaker at 8 Ohms. But don’t plug them to 4 Ohms cabinets, it may brake the amp and its cab.

Tubecake loudness

Q: How loud is TC1 and TC3?

A: TC-1 and TC3 are both have more than enough volume for home practice and studio recordings. TC-3 has more headroom compared to TC-1. They both can power 8Ohm 1×12, 2×12 or 4×12 cabs. TC-3 has enough volume for small reheasal rooms and can compete with a drum set.
