Hello guys,

Few days ago I bought a second-hand Blackstar s1 200. It Plays great but I noticed that transformers are covered in some kind of a greeny stuff. What is it? Is it considered normal?

Thanks for help

Yeah.. That's what I thought about first.. But I have never seen anything like that before on any tube amp... :/
Not glue, I'm pretty sure it's an anti-corrosion film.
