Dos Ochenta Compressor Rev.4.Jan.17.2005

Build the DOD 280 compressor on this layout. An LED/LDR can be used instead of the VTL5C2. Millennium 1 added to the circuit board, if it is not desired, just leave those parts out. Off board components except for the potentiometers are not shown on the layout. Trademarks are propery of their owners. 500k-B
