Help with Atma-sphere MP3 and DC offset

I have a MP3 preamp.
I have tried several Raytheon VT231 tubes, and all of them, after a few working minutes, light the preamp DC offset red lights.
The manual says that, when these red lights stand on, the preamp must be switched off inmediately, because of DC issues.
Is it really dangerous, when these DC offset lights keep on glowing?
Maybe it is a compatibility issue between the MP3 and the Raytheons?
The amps are Atma-sphere M60s.
I´d like to use these Raytheons because I like the sound. I also use Tungsols WGT, maybe somewhat lighter.
Thanks in advance
