Hi - I'm Harry Axten.
I'm a design engineer from Guildford, UK. I'm particularly interested in electronic musical instruments and products for music production. This website shows some of the things I have worked on in the last couple of years.
I'm also available for synth repairs, servicing and modifications.
You can contact me at : harry(at)hkadesign.org.uk
Please note I am only able to offer support for kits that were originally built & sold by me, or by Werkstatt Matlak in Germany.
There are some unauthorised clones of the TR-505 and TR-626 kits floating around, based on old revisions and often sold as full DIY builds. I have no association with these sellers do not provide any support for these.
