Resistor on a post in CRT monitor?

(1/2) > >>

gmc:
I'm busy trying to repair a old 12" CRT from the early 80's - Yes, I'm  aware of the electrical dangers  ;)

One of the components is a 56R resistor which is now reading 100R. Looking at the schematic it's a 56R RN1/4 which from what I can gather is a 0.25W Metal Film Resistor.  Resistor looks a bit worse for wear and has overheated.

That's all good and easily replaceable. One thing that I've noticed is that there are a few resistors around the HV side that have one leg soldered to a post which I've not seen before.

Guessing it's to keep it off the PCB for cooling? But why one leg and why mount it to a post? (Or is the post also some sort of heat sink?)

Was this a standard for the CRT's in the 80's?

johansen:
Usually 2 posts were used to keep the heat away from the board

jonpaul:
post keeps HV arc to PCB surface eg dust.

Very common.

Use carbon comp resistor rated for the HV

gmc:
Thanks for the info. Will source the correct resistor replacement.

inse:
You can see the windings, this isn’t a carbon composition resistor but a metal film type.
