OK - so forgive me for being not too quick on the uptake but I need some carefully considered advice.
The Dynaco has three output taps. 4, 8 and 16 ohm.
So if I'm running a pair of reasonably efficient speakers, say, 8ohm Klipsch Cornwalls, what's going to happen if I hook them up to either the 4 or 16 ohm taps?
The ST-70 puts out about 35wpc at 8ohms. a bunch more at 4ohms? A bunch less at 16?
What's going to happen? I'm sure somebody has taken a run at this and has somewhat of plethora of sage wisdom to impart and I have a need to know.thanks

Follow Ups:
Try the 4 ohm tap. Dynas work better at listening levels with 4 ohm drive. The Cornwalls may not hold the 8 ohm impedance over the whole range, as well (I am former Cornwall salesman).
Well John - a guy has to start somewhere doesn't he!
Thanks a bunch for that tip. I'll give it a shot - I'm at the start of doing a couple of tweaks with the cabinet and the internal wiring - which should only take, like, forever. (It's getting to be Springtime in Alberta - if I might swipe the title from a song of one of Crump's favourite writer/performers - and the honeydo list is getting longer by the day)

On a tube amp with an output transformer, you don't have the increase in current draw when you hook up a lower ohm load like you get with a transistor amp.Basically, using the correct tap is important to match your speaker load to the tube's needed output impedance. Using the wrong tap probably won't damage anything, but you may reduce sound quality and you certainly won't be getting any more power.
I wasn't looking for more power. I was thinking about less power actually.
I'll give them all a shot and see what comes up in the way of lucid sound reproduction.
