The Hand of Light was designed by Gustav Grinderslev as a simplified take on a solid state optical compressor, using the topology of the UREI LA4 as a starting point. The circuit and construction have been simplified to allow for entry-level use. Case, mounting hardware, power toroid, and output transformer are not included.

Features:

• Electronically-balanced input stage, transformer-balanced output
• Vactrol optocell-based compression stage
• PCB separated into sections based on circuit topology stages, wide pads for easier soldering

Price:

• n/a
• n/a
