Think there's a pretty fundamental problem getting transformers to work
well at an extreme turns ratio. Like a match for 1 ohm.

When I wrote the earlier post, I was actually thinking of nominal 3 or
4 ohm loads which give problems to many lesser SS amps as their
impedance can dip below nominal, but can be matched quite well to valve
amps. I agree that it's a challenge to make a transformer work down to
1 ohm, especially at low frequencies, but possible given enough iron
and good winding technique.

It may well be but far easier (and cheaper) with SS. In other words a
cheap valve amp will have *more* problems driving a low impedance load
*properly* than a cheap SS amp. Of course the SS amp may simply blow a
fuse while the valve amp burns out its OPT. ;-)
