Restoration complete. Had to purchase a matched pair of 6U8's. Matched Sylvania's are what came. The channels matched up quite nicely. Set the bias for the outputs at 65 ma, a fuzz low, and set the balance. Frequency response is very smooth from about 50 to 20K. Starts rolling off below 50. Hooked it up to my Legacy Classics in my studio and powered it up. Sounds great! Better than I expected, even comparing it to my mono blocks. Very pleased.
