    Hi Simon, There could be a few issues, if you refer to page 6 in the following it shows a fault finding guide, within this there are steps to look at if the outputs are not working. If you have checked all of these and it still doesn’t work, send a photo of the top and bottom of the circuit board to support@kitronik.co.uk and explain the issue you are having.

    Hi Abinasch, The kit comes with all the components required to build the kit, however you would need to have additional tools such as a soldering iron, solder, screwdriver. A full list of what is required to build this kit can be found on the product page under the heading ‘Requires’

    Hi Sam, We don’t currently sell a Bluetooth add on module, off-the-shelf modules do exist though and should come with instructions for connecting to an amplifier. However we do stock a Bluetooth amplifier which would be a better option, https://www.kitronik.co.uk/c2160-bluetooth-stereo-amplifier-kit.html

    Hi Jane, We are currently awaiting a new batch of PCB’s from our supplier, we expect to receive these later this month and will hopefully have the item back in stock early February.

    Hello Jack, when the question was asked back on 20th of December it was the power supply that was out of stock. This time the issue is caused by the high powered amp kit components and PCB. We are awaiting an order for the PCBs and we estimate that the kit will be back in stock early February.

    Hi Arda, We are currently expecting the item which is causing the product to be out of stock to be in stock in the next day or so. We are hopeful we can ship any back orders before we close for Christmas.

    Hi, unfortunately we are unable to swap the lead in the kit for the newer version of the IPod lead. You also wouldn’t be able to swap this yourself due to the old 30 pin lead had 2 pins for analogue audio, the new lead uses digital audio that needs a special converter to work with any standard audio equipment.

    Hi William, The high powered amp kit requires a voltage of 12V’s and draws around 2A, as such it does draws a large amount of current due to the nature of the amplifier being a high powered amp. If you’re looking for a lower current draw amp then the 3W class D amp might be a better option as it draws around 600mA, https://www.kitronik.co.uk/2158-3w-class-d-stereo-amplifier.html

    Hi Thomas, you could technically run the kit from batteries, however it requires a 12V supply and will draw around 2A. So if you used 8 AA batteries (to give the minimum supply voltage required) these would be drained in around 1 hour’s time. As such we wouldn’t recommend using batteries.

    Hi Ben, It is technically possible to do this, you would connect each crossover to the terminal block (as shown in the following link https://www.kitronik.co.uk/blog/use-2-way-passive-crossover/) and also the speaker wire to the terminal block as per the build instructions. However it is possible that there could be a delay from the speaker playing a signal to the woofer and tweeter playing the signal, so you could get a bit of an echo. Also you may get a little interference from the full range speaker through the crossover. If this is the case I would suggest removing the full range speaker. Hope this helps.

    As long as the max power of the speaker is at least 15W and it is an 8ohm speaker then it will be fine to use with this kit. So yes the speaker you ask about will be fine.

    If the power is significantly over 15W then you will be paying extra for a higher power speaker but won't be able to drive it, it therefore doesn't make sense to use a speaker that is more than 50W with the kit.

    The IPod cable is an input cable only and as such wont charge the device.

    Unfortunately the IPod cable supplied isn’t compactable with the lightning version or above, and we aren’t able to provide one that is compactable.

Jerry Rolfe sent us this image of an old army water can, which he has retro fitted with our High Power Stereo Amplifier. The amp is fitted to the back with the power lead feeding in through the bottom of the can and the 3.5mm jack lead leaving the top of the can. According to Jerry It sounds awesome!

High Power Amplifier Kit – Dan Thwaites
Dan Thwaites sent us these pictures of our High Power Amp kit inside a 1952 German valve radio that was no longer working. He took out the original components and installed the Amp kit. The volume control knob still works as he fitted the potentiometer to it and wired it back to the PCB. The dial faceplate was also originally backlit by two bulbs, so he replaced these with two white LEDs wired in parallel off the board. He also had to extend the power and headphone sockets to fit around the original chassis.

How to use a 2-Way Passive Crossover
A crossover is the name given to a circuit that splits an audio signal into separate frequency bands. This allows different frequency bands of the output from an amplifier to be sent to different speakers instead of all being sent to one speaker.
