Well, Mike-in-Virginia, the Dyna Stereo 70 that I made back in '62 is still with me but not in use, though every so often I think of putting in one of Van Alstine's mod kits and firing it up again. I wonder how it would sound against the nOrhs - aside from the 12-dbw output level difference, and assuming the 990's output has the impedance to drive it. (Steve, can the 990 drive tube amps?) And the 990's phono input (which is why I bought it) works fine with my AR XA turntable, now 43 years old and running fine, though I mounted a Mayware Formula V unipivot arm on it only 20 years ago. Any other good old stuff out there? Lowther speakers maybe?
