Hello, this my first post and I hope will not be my last. I would like to build a tube amp for my Magneplaner 1.6's. I have rebuilt a Dynakit ST70 as a class A amp and enjoy its sound quality when driving my efficient cone speakers. But of course the ST70 can not drive the Magneplaner at any volume without clipping and blowing the speakers fuse. I have a pair of Dynakit Mark 3's that need to be reworked, could these 60 watt amps drive these speakers? I would prefer not to spend the money on the Mark 3's and then find out that they can not drive the Magneplanars. I think an amp able to produce 100 watts would work, are there any recommendation? Thanks.
