Need advice

I am new to this and need advice .

I have just become aware of some hiss coming from my preamp, Audio Research LS 2B Mkll. Think it might be caused by the tube ? Current tube Electro Harmonix 6922,

What tube should I replace it with for least noise and best sound?

Is there anything else I need to do ?

Always the first place to start, most likely. With Audio Research gear I don’t tube roll. I’d get a brand replacement or similar. But that is me.
