HP 141T DISPLAY SECTION

Dismantled for Spares

Front View
This was the state of the HP 141T Display Section before dismantling.  With the plug-in IF and RF Sections, the Display Section was working and a Spectrum Analyser trace obtained.   
 
The HP 141T 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 have the original HP Service Manual to help identify all the spare parts.

I have repaired a lot of HP equipment and usually start by dismantling to assembly level to clean everything up and inspect for any obvious problems. Normally an easy process, just take lots of photos and notes, occasionally have to desolder a wire or two, then reassembly. 
 
Not so with the 141T, this must have been a nightmare to manufacture! Complicated wiring looms and lots of individual pin contacts to the pcb's. Must have been a design throwback to valve (vacuum tube) technology and metal chassis. Cableforms pass through holes in metal panels, so impossible to remove. Some parts riveted on instead of screwed. Usual problem of connectors on front of panel with wiring behind, so again can't be removed. I didn't want to cut the cableforms, so had to cut the panels instead.
