Dave, I was aware of changes in the sense of smell from coronavirus but didn't know about similar effects from the vaccine. I can't say I noticed any changes in my sense of smell after my vaccines but had an array of other side effects.

I suppose I've always had a keen sense of smell but in recent years old familiar smells which previously seemed good are not welcome these days.

Talking about odours from plastics, some cheap plastic products from China have a horrendous smell and I bet they're probably toxic. Has anyone else noticed this?

When I bought my HP counter/timer (5328A - fan cooled) it smelled for all the world of cat urine.

Turned out to be the reservoir capacitors at end of life, venting goo. Replaced them - smelly problem gone.

Nick, no signs of that in the wiring which otherwise looks in good condition and is still very flexible.

Good points from emeritus re PVC in enclosed spaces. Also restoration73's mention of the hazard with PTFE is important. Other than the toxic fumes given off when heated, I believe hydroflouric acid can be produced if it is burnt at high temperatures which is nasty.

Thanks also to Lucien for your interesting post.

Funny old thing, smell. Hyacinths smell like burning plastic to me. My wife cannot have them in the house now as the smell sends me hunting for something overheating.
