I have a parts 475. Tim

The manual lists this as 152-0488-00. They are available from many sources. NTE 167 is an alternative: http://www.nteinc.com/specs/100to199/pdf/nte166.pdf This is a gumdrop component available from

Lots of intriguing and cheap items added to the page including a rack-mounted Z3801A GPS system for precision 10MHz signals: https://www.sphere.bc.ca/test/stuffday.html#calfans Some rare Tek items

Just wanted to thank everyone. The monitor is now working better than ever and fully aligned to D65. Jonathan
