Original phono prototype August 19 2012, 0 Comments

I was digging though some shelves piled with audio stuff and ran across the original BHL phono prototype in all it's point-to-point-on-a-ground-plane glory.
The idea for the method of construction comes from Ham Radio projects where the frequencies are much higher than audio and the grounding is critical.  It is pretty easy to slap something together this way, but I wouldn't want to do anything much more complex.
