Dusted off the old Dynaco St-70 on the 4th of July. I usually don't use this during the summer months because it generates a fair amount of heat.  I put a fresh set of JJ E34L's in this a few months ago.(That's no typo- they ARE E34L's -they do draw a little more current than a stock EL-34, so do your homework before you substitute them for the EL-34). How does the amp sound? Well, it gives up a little bit of bass definition compared to the McIntosh 2100 power amp it displaced- but makes up for it with a wide and deep soundstage and euphony that kept me listening until 4:30 in the morning. The sound improved markedly after the first hour, and once warmed up is a desert island pick. Or perhaps better referred to as a deserted island pick; with that kind of heat, the Aleutian Islands will certainly do.
    Thanks to Chris J. for the inspiration to dig this out, and for bringing a Thorens turntable and some vinyl for the occasion.  The pre-amp was a Luxman R-115 receiver. Speakers by Dahlquist. DQ-10's to be precise.
