HP 3764A DIGITAL
TRANSMISSION ANALYSER

FOR SALE

Dismantled for Spares
Front view
This was the state of the HP 3764A Digital Transmission Analyser before dismantling. Top cover and printer module missing and some minor damage inside. 

The HP 3764A has been carefully dismantled down to 'Assembly' level so that I can cannibalise parts for use elsewhere, or maybe some of it will be useful to someone else to repair their unit. Please Contact Me if you need any of these parts.

I now have the original HP Service Manual to help identify all the spare parts.
