It’s been a month since I last posted. Now getting back to the Fyrall project. I’m calling it Fyrall Mutant, because I’ve made a number of modifications from Peter Blasser’s original design. All will be detailed in a future post. Today I finished drilling and filling the plexiglass case.

The Fyrall PC board is mounted beneath the surface with four board-mounted pots and two standoffs holding it. The nine board-mounted LEDs show through. The remainder of the panel is taken up by all the ins and outs and switches.

There’s going be a good deal of wiring next. Wires will go from the component side (underneath) to the panel. Here’s what the underside looks like.

You’re looking through the bottom of the case. I’ll be reworking the standoffs, replacing those nylon ones with machine screws.

Added this pic of the bottom wiring mostly done. I’m still waiting for the right DPDT switches to be delivered. It’s all working. After I add the range switches and capacitors, I’ll make a video. The labels on chips helped me to wire the panel according to the oscillator pairs that share a rate pot.
