Our best selling amplifier kit has had an upgrade and a facelift. Version 2.0 of our Pre-built Mono Amplifier Kit has a brand new IC and we've also made all of the components suraface mount for a neater design.
This audio amplifier kit can be used with any personal stereo equipment, including MP3 players. It uses the very polular LM836 audio amplifier IC which can output 0.7W of power. The kit is supplied with a PP3 battery clip and can run off any voltage from 4 to 15 volts.
Also supplied is a pre-built jack cable.
All that is required is to solder the jack lead, speaker & power clip to the board and you are good to go.
- Pre-built kit allows you to concentrate on product design rather than assembly.
- Works with a wide variety of mp3 players, phones and computer equipment.
- 1 x Pre-Built Mono MP3 Amplifier.
- 1 x PP3 Battery Clip Lead (Heavy Duty).
- 1 x 3.5mm Mono Jack Lead, 50cm length.
- 1 x 8 ohm 66mm Speaker.
- PCB Length: 45.5mm.
- PCB Width: 35.5mm.
- Mono Amplifier Essentials (Including Build Instructions).
- Teaching Notes (Including Essentials).
- LM386 Datasheet.
- Cutting Files for our Mono Amp Case.
- Please note if using 2D Design the .dxf file can be opened by using File -> Import.

Jeff Draisey, head of D&T at the Balcarass School in Cheltenham, sent us these Year 8 70's themed Mono Amplifier Projects. We think you'll agree the students not only did a great job with the research, but produced some excellent looking results too!
James Ratcliffe, Director of Design & Technology at Milton Abbey School sent us these great examples of Year 10 work based around our MP3 Mono Amplifier Kit.
This week we have a guest post brought to you by Phil Wickham of Dixons Trinity Academy, whose class have made some concrete speakers using our PIC Controlled Mono Amp Kit.
Northfield School's D&T Department (@Northfield_DT) have shared these MP3 docking stations with us on Twitter. End of year assessments - DONE - great work!

You may not have noticed but we've recently introduced a new Cardboard Mono Amplifier case that offers an extremely cost effective way of housing an amp, that is part of an electronics-focused practical task, without having to spend weeks on the enclosure.
This resource has been designed to show how you can use our Mono and stereo amplifier module kits as the basis for a 3D printing project.

Can I use the prebult mp3 mono amplifier with a crystal radio set?
Posted byon Wednesday, 7 December 2016
Hello Roger, It is possible to add another amplifier to the output of the radio kit, however the mono amp kit wouldn’t be a suitable option. The 3W class D amp kit would be a more suitable option. I have assumed that you are using our FM radio kit for this, other kits can be different.
Is there any chance of ordering just the pre-built amplifier board? I have plenty of speakers and battery snaps, but have run out of boards.
Posted byon Wednesday, 28 September 2016
Hi Tony, Unfortunately we are unable to supply just the built boards. This is due to us having speakers and battery clips automatically ordered when a batch of these boards are built and as such we wouldn’t be able to separate these out.
What is the optimum input impedance for this amplifier? I have a high impedance source (4Kohms) and need to match it to this unit. Thanks.

If you take a look at the input biasing on page 3 of the chip datasheet this explains further. However with how the kit is designed your input impedance should be fine. https://www.kitronik.co.uk/pdf/LM386.pdf1 people found this answer helpful.
