biasing for 4 ohm speakers

I recently switched from 8 ohm to 4 ohm speakers with my Jolida 502P. The 8 ohm speakers were connected to the 8 ohm taps and I now have the 4 ohm speakers connected to the 4 ohm taps. Will this require a bias adjustment due to the change of speakers and taps?

The bias point on any tube is a DC value.

The DC voltage drop across the output transformer is not going to change significantly even if the 4 ohm load is on the 8 ohm tap which it isn't in this case. The short answer:

'No.'
