It's definitely recommended. It's like changing the spark plugs on your car without adjusting the timing or the fuel mixture.
If you're lucky, the new tubes will want the same bias as the old ones and will sound great. If you aren't lucky, the amp will sound lousy. And if you're REALLY unlucky, you could blow tubes and damage the amp.
