I'm hoping to get a definitive answer regarding replacing the EL84's in my HT20RH MKII.

Do they or do they NOT need to be biased? (I know that the pre-amp tubes are plug and play).

I have found nothing online or in this forum regarding this particular amp.

Thanks in advance for some constructive feedback (no pun intended).
