I have some octal Aikido mono PC boards which I had made from design files posted on DIYaudio. If you'd like a pair I'll send them for shipping. They are the audio circuit only and will need a power supply of your choice. The Neurochrom reg is great, I've used them but the Aikido just need a good supply.
I'm sorry it seems that you or someone moved or deleted I subject that I posted in reference to a pair of Tannoy Arden speakers. Have I done something wrong? I thought I posted in the area that seemed to most closely match the subject?
