Hello everybody. I have started having a specific sort of problem with my compressor. It's a Medea TigerShark that I sort-of inherited from a friend who got out of airbrushing. As you can see in the linked video, after I have been using it for a while I can hear this increasing hissing noise coming from a brass valve. It builds for a bit and sometimes just continues at that level, or sometimes it releases the pressure with a loud pop/hiss that makes me jump every time (it's loud in real life). Other than this the compressor works just fine. Is it toast? Should I keep using it despite what looks like some kind of emergency release happening? Will it eventually blow my legs off, Saving Private Ryan style?
