Remote symmetric matchbox - part 2

I finally got to soldering the PCBs for my tuner. Here is the picture of the result hooked up to my Bus Pirate for testing:

The capacitor board can switch in capacitances between (design values) 3.7pF and 947pF.

It consists of 8 binary switched banks where each bank has three sections in series (to increase breakdown voltage) with two caps in parallel in each (to improve current carrying capability). All capacitors are zero temperature coefficient (NP0) ceramics rated for 500V.

bank	total	section 1	section 2	section 3
1.	3.7pF	2x 5.6pF	2x 5.6pF	2x 5.6pF
2.	7.5pF	2x 10pF	2x 12pF	2x 12pF
3.	14.7pF	2x 22pF	2x 22pF	2x 22pF
4.	30.3pF	2x 39pF	2x 39pF	2x 68pF
5.	57.6pF	2x 68pF	2x 100pF	2x 100pF
6.	120pF	2x 180pF	2x 180pF	2x 180pF
7.	231.9pF	2x 330pF	2x 330pF	2x 390pF
8.	480.7pF	2x 680pF	2x 680pF	2x 820pF

Once I (create and) connect the toroid board and input balun, the tuner will be ready for field testing.
