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.

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.
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.
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.pdf
