Had no problem tube-rolling in my SQ-N10. To my ears it was best with Soviet era 6P14NP tubes, which I still use in my Cary amp to good effect. Found no need to set the bias, though perhaps it would have been even better if I had. Here is a pic of the current SQ-N150. No more often than one needs to set the bias it wouldn't stop me from owning another if I had compatible speakers. Terrific little integrated amp.
