    Have talked with Roy and Dan about rebuilding my ST70 into a ST120 for a while now.  I've finally pulled the trigger, bought the parts, and have finished the rebuild.  Driver tubes are EH 12AU7s and output tubes are Svetlana OTK 6550Bs.  Sounds great!  Now to build another ST70 from my leftover parts.  vta st120 - ST70>ST120 1f60e
