JB12T is the one unit in this family photographed as a real bench sample rather than a studio render — six photographs, including close-up shots of the connector panel and the gland-side wall. The panel carries channels 01–12 across two rows of six, black powder-coated steel, a screw-fixed flat top panel (roughly 8 screws — 4 corners, 4 edge-midpoints), and two light-coloured nylon cable glands stacked vertically on one side wall. Rubber feet on the underside complete the build.

Because it is the most thoroughly documented model, JB12T is the anchor for construction details asserted elsewhere in this family’s copy (screw-fixed cover, no hinge, rubber feet) — where another model’s page notes a detail was not independently confirmed, JB12T is the nearest confirmed reference for that detail, not proof it was separately verified on that model.

This is a passive assembly with no active device in the signal path. THD and noise-floor figures (≤ 0.001% / ≤ −120 dBV, reported on request) are null-result measurements confirming the assembly adds no detectable distortion or noise above a calibrated analyser’s own floor — not a spec the box “achieves” the way an active instrument would.
