I stand corrected. Both materials have the same base odor.

Phenolic is used as an insulator for stepper contacts and also was used extensively for printed circuit material before the glass-epoxy material became the standard. It's also used on all leaf switches as insulation between leaves.

Bakelite was the material of choice for early automotive distributor caps and oven knobs among other items.

I have to say I agree.

The four machines in the basement include

2 Gottliebs
1 Bally
1 Williams

They truly all have a distinctive smell, but I can tell the 2 Gottliebs are similar.

It's probably soaked into spots on the inside unpainted wood.

Go to PetSmart and buy a bottle of Natures Miracle Urine Destroyer.

Soak the areas that smell the worst.

The enzymes will he'll eat the urine away.

I've seen ozone mentioned a few places as a smell unique to EMs - what causes that smell?

They smell like old library books to me. Based on that I always assumed it was the wood creating the distinctive smell.

Whiskey bottles, and brand new cars
Oak tree you're in my way
There's too much coke and too much smoke
Look what's going on inside you

Oh that smell
Can't you smell that smell
Oh that smell
The smell of pins surrounds you

Yes, 1973 I'm home again...

Ozone will fade fairly quickly. It's the cloth wire wrap.

To me, certain clean Gottlieb pins from the '60s have that warm woody aroma. Just intoxicating!

Smells like Victory!
