Have searched the web on this subject, only to become more confused than ever.
So many differing views.
Q - Is it okay to drive my 16ohm speakers with a 8ohm valve amp ?

You won't hurt anything. It's low impedances you have to be careful with.

Thanks lads...So I can disregard this sort of posts and similar.
If the amplifier in question has a vacuum tube (valve) output coupled through a transformer, you will need to use two 16 ohm speakers in parallel for each output channel (because the parallel combination is equivalent to an 8 ohm speaker). Otherwise you may damage the output tubes.

Not sure what you're saying. You don't need to run paralleled 16 ohm speakers, but you can if you want to. You won't damage the amp either way.

Not sure what its saying either to be honest wal ..!!
It was a quote from the web, like I said loads of em all of differing opinion.

Speaker impedances are a dynamic thing and a quoted say 8 ohm load is merely nominal. The actual impedance is quite likely to vary across the frequency range, rising above and falling below the 8 ohm figure across the range.
It really is nothing to worry about, just don't use silly low impedances like one or two ohms. You probably won't damage a valve amp if you do, but the sound may not be at its best.
It's a different story with transistor amps. Very low impedances can fry them!
