Franco has used one of our amps, a Berning ZH-270 for years, as a design reference, so no problem with 70 watts at all!
A lot of people have success with regular OTL's and 4 ohms speakers, so that should not be a problem either, however this is never a problem with the ZH-270 as it has a unique way of matching speaker impedances.
Good luck.
Allan
