Description
Stereo TDA2030 Audio Amplifier DIY Kit with Tone control V1.2 comes with an improved circuit design, and only requires a single supply voltage of 12-30V.
On board are controls for volume, bass and treble.
The input is a 3.5mm stereo jack that can connect to any MP3 player, phone or TV with a stereo audio output (e.g. headphone port or RCA ports).
The kit is easy to assemble – just follow some helpful instructions:
NOTE: Always watch the polarity of electrolytic capacitors, integrated circuits and diodes! The long lead on the caps is [+] and the marking on the body is [-]. The diodes have a ring printed on their cathodes [-].
- Install all the parts, except the TDA2030, beginning with the lowest profile (resistors), and finishing with the tallest (potentiometers, heatsinks and large capacitors).
- Next, you install the TDA2030 into the holes on the PCB and affix them to the heat sinks using the screws in the kit. The final step is to solder the 5 leads of every TDA2030 to the PCB.
- After double-checking all solder joints and the position of all parts, you can supply your module with power. The idle current, with the volume potentiometer turned to the lowest level, should not exceed about 50mA. If the current is higher or even your supply voltage drops or shortens out, YOU need to do troubleshooting.
The typical output power is about 2 x 15W on 4 Ohm loads (speaker) with a power supply of 24V.
The Stereo TDA2030 Audio Amplifier DIY Kit with Tone control V1.2 includes:
– circuit board
– all parts to assemble
– 3 potentiometer knobs
– 2.1/5.5mm DC jack (not in the picture)
– 2 speaker terminals

Suprisingly clean and powerful sound, given it’s cost and size.
Fun kit and a nice amp – great to get back into kit building (after several decades away).
Some notes:
– lots of small passive components – keep a magnifying glass handy, work slowly and triple-check everything.
– some values printed on the pcb don’t match schematic (R8, R9, R11, R12). When in doubt, trust the schematic.
– be sure to use a CLEAN power supply – had an awful 60Hz hum until I powered it off a 12v battery.

Surprised to discover this shipped from Canada and the back-uo via email was positive. Will be using this as a back-uo amplifier for general bench use

What you get for 15 bucks here is pretty impressive. As a soldering kit, it’s a nice way to spend an hour or two… ideal for anyone who wants to dip their toes into amp design. As with all of the Canaduino kits, the PCB is high quality, silkscreen is clear and there are no inconsistencies that I noticed between the board and the schematic. Minor thing, but I think it would be cool if some of these kits shipped with some standoffs, as the PCB is cut for them. I received a whole bunch of extra resistors and ceramic caps on all of the 4 of these I’ve bought, which is always appreciated!
But the actual amp? I was pretty shocked at how well it performs given the price. There is, as expected, noticable noise in the absense of audio playback, but it is pretty well inperceptible when you are playing audio. The amp is quite powerful, if you really push it through some quality speakers, it’s perfectly capable of rattling your bones, and distortion at high gain is respectably low. The TDA’s come with heat sinks, but they don’t seem to run terribly hot in any case even without the sinks. Certainly no harm in having them though.
The filters are clearly well thought out; both the bass and treble pots are quite sensitive. The distortion is at its worst if you push the highs, but seems like that’s to be expected given the characteristics of the IC’s. Sending the output into my passive bookshelf speakers, I tend to keep the bass around 9 o clock, treble around 12.
As Rusty pointed out, you’ll want to think about using an isolated power source, I also encountered a 60Hz hum.
This thing is a daily driver for me as the amp for a bluetooth turntable system I put together recently… and it’s the cheapest part of it.
I love this kit… it’s a no brainer if you’re into audio.

Thank you for the great feedback. I built my first TDA2030 amp in 1988, and I only had a big old 100W transformer 2x12V and didn’t have any big caps and no experience at all. I just wanted to build my own amp. And I did. The hum was so annoying, that I gave it away shortly after. Today we have switching wall-wart PSUs, clocking somewhere at 100kHz or higher, and are perfectly fine for simple amps.
The thermal noise (Johnson-Nyquist noise) that you can heat at low volume is most likely coming from the cheap potentiometers in filter network and volume control. The other resistors are also noisy, but probably not as much as the potentiometers.
It is always a compromise to offer an affordable kit for hobbyists. Using high-quality audio potentiometers would double the price of the kit.
