[Test-Equipment] HP 8601A Sweep Generator

[Ronald KA4INM Youvan]

   Yes, and it's much thicker than any fiber optic light guide I have ever seen. 
  It is the decimal point between digits on the veeder root counter that is the 
center or stop frequency readout.  There are two lamps and two light guides, one 
to show .1 to 11 mHz range and one to show the 1 to 110 mHz range.

   It is some kind of clear mono filament, vinyl looking clear plastic cordage 
and time has not been kind to it.

>>I just acquired a HP 8601A Sweep Generator (and 8600A digital marker/
>>counter) and the page 6-17 item 34 "special lacing cord" type EP127
>>both pieces are fractured beyond use.  (both lamps are operating)
>>   What has been successfully used to replace these light guides?
>>Have LED's been used to modernize this "range indicator"?
>>If so how?
