This is an auction of one piece of bare PCB of Quad 405 and the matching T-shape heatsink . The heatsink is black anodized and pre-drilled so users save time in processing the heatsink.
The T-shape heatsink is to mate to a big finned heatsink as in original Quad 405. The T-shape heatsink itself cannot offer enough surface area for heat dissipation.
