Description

This circuit board has a remarkable, irregular array of transistors, capacitors and resistors. A hardened residue on the solder side is in a regular line around three sides as if at some time there might have been a cover attached with adhesive; however the residue is also in blobs around solder points as if it might have been solder flux.
