I just finished one channel on these. Just thought I would share. I may add a purple heart face plate to each of them, but I am not sure. It is the Poseidon schematic, but Point to Point, so I did not put it there. That board was at my local surplus shop for fifty cents. Makes a great narrow cap board. I also pulled the multicap and added another bias pot for individual bias. The drivers are mounted to a piece of 1/4" plexi that I plan to light up with an LED eventually off the filament winding. Turned out really nice even though it is sloppy:)

The best part is that I have less than $300 in the pair.

Hi Mark,

Here you go. Not quite what I was going for. I would have loved to put the drivers closer to the edge and left more open space for an illuminated plexi panel, but now you can see all the wire work. I'm keeping them for a bit anyway, so it is all good.
