Burn in after repair?


I had an amplification unit repaired with output and driver transistors replaced in one channel.  In starting to listen to the unit after repair, I find the sound somewhat thin and bass shy.  How normal is this?  Thanks for your thoughts/experience.

     If it doesn’t start sounding better, after a reasonable time powered up/in service: have the builder/Tech check the Bias.
