2x3 / 1x7 Buffer

Maker	Gerbster
Type	Active buffered multiple, either two 1-to-3 blocks or one 1-to-7
Mounting	Through-hole
Width	—
License	Proprietary (No licence published)
Difficulty	🧊 Low-count through-hole

TL074 and TL072 based. The last output of the first block is linked to the second block's input, so with nothing patched into input two it behaves as a single 1 to 7 buffer.
