Just curious as to the reason for 8 ohm speaker output only. I assume it had to do with the particular OT that was chosen?

Keeping the cost down and not reordering/redesigning the OT for multiple taps allowed us to keep the end-consumer price point much lower and for much longer than you would typically expect this amp to be. Impedance mismatches in either direction are generally safe with all of our OTs.

Either is pretty safe, parallel will theoretically be more stressful on the tubes, series will theoretically be more stress on the OT, and this is only if you are really winding the amp up and driving it hard, repeatedly, for hours and hours, days and days, lots of abuse. And in this case, bet on the OT over the tubes. So series.
