OK, so you're really saying, all in all, the 4 ohm tap would be best then?
I'll give it a try and see if I can hear an improvement.

Thanks for that - nice to get information from someone who *knows*.... ;-)




Only other thing to consider (don't disagree with what Stew has posted)
but using the 4R tap with 8R speakers, will mean the output valves see a
reflected load thats 4 times bigger. Thi sis good in that it will tend
to reduce the distortion, but it will also severly limit to output
power, maybe more than the advantages of using the 4R tap give.

Thats why I originally mentioned reflected loads and load lines.

OK, I'm taking it as 'tap down for less distortion but quieter' and 'tap up
for louder but more ragged' as a general rule of thumb then.

Succinct, and accurate! :-)
