I’m John and I like to make and use old school hifi gear. I built my first piece of DIY audio using a small class-d 5W amplifier kit I bought from Frys. It sounded awful but got me hooked.

Builds I post here is stuff I’ve made, but I may not have designed it. I’ll make sure to attribute the right folks. I also sell stuff on eBay. Usually builds I’ve retired or if I happen to have some spare parts. That sort of thing.

Want me to make you something? Get in touch and lets make it happen.
