Steve Fergusson, the Head of DT at Haywood Academy in Burslem Stoke on Trent, sent us some excellent examples of innovative student designs for Amplifier and Lamp cases. The cases were designed and made by GCSE and A Level Product Design students and display a high level of creativity in all of the Students involved.
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!
We visited Merchant Taylors' School and we saw some amplifiers designed by some of the students using our High Power Amplifier Kits. We were very impressed with the range of upcycled materials that were used to design the case of the amplifiers.
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.
James Stapling sent us these images of his oak high powered amplifier case. The cable tidies away into the box when not in use and it has a nice little oak volume control.

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.
Hi How would you recommend attaching a bluetooth receiver to this circuit? And if i can attach a bluetooth receiver how would i be able to attach the receiver to the same power supply as the amplifier? Thank you.

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, I need one of these kits for my GCSE project and see that you have said that they should be in by Feb but is there a way I can guarantee getting one by then as I will have to find another option if not? Thanks Tom

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 my question is in connection with a previous question i noticed you said the product should be back by the 20th of December and i just went to buy this product and it says it is out of stock please tell me you will have stock soon.
Posted byon Wednesday, 11 January 2017
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.
