We Have Sold Our 250,000th Mono Amplifier!
Back in June 2014 we sold our 250,000th MP3 Mono Amplifier Project Kit, making it our best selling project kit so far! Having smashed the quarter of a million mark, we're dedicating this week's Newsy-Blog to the mighty Mono Amp Kit itself - keep reading for more details, for Mono Amp Gallery images, for an insight into how the Mono Amplifiers are kitted/manufactured, and more!


The Mono Amp Kit is one of our intermediate project kits, designed by Kitronik to suit Key Stage 3 abilities. This audio amplifier kit can be used with any personal stereo equipment, including MP3 players, and uses a TBA820M Audio Amplifier IC, which can output 1.6W of power. The kit is supplied with a pre-built jack cable and a PP3 battery clip, and can run off any voltage from 3 to 16 volts. With the MP3 Mono Amplifier Kit, all of the components have to be soldered onto the PCB. However the pre-built version allows you to focus more on product design as all of the resistors, capacitors and the IC holder are fitted - all that you have to do is connect the jack lead, speaker and power clip to the board.

How do we keep enough Mono Amplifiers on the shelf considering the popularity of the kit?

It is imperative that we keep on top of our stock levels. We have minimum stock levels for every product that we have and we (and our database system) keep a close eye on what needs ordering, building, kitting, etc. As soon as our Mono Amp Kit stock levels drop, we place an order with our suppliers for the parts needed to make up 1000 kits.  As soon as they arrive to us, we ship them out to our home workers who - believe it or not - work from home, packing each component into bags to make 1000 individual kits. The kits are then returned back to us where one of our warehouse team will box them up and add them to stock, ready to be shipped to you, our customers! It is a similar process for the pre-built Mono Amp with the exception that the parts are sent to an Engineering company to be assembled. Some of our kits are built in-house but this depends on the kit and the quantity that needs to be kitted/soldered. 250k_mono_amp_blog_560_18
