Many times Frank answered the phone when I called, always helpful. Met him once at an audio show in Detroit prolly 10 or more years ago.
My college roommate sent me some an old ST-70 Dynaco amp that I then sent to Frank for reworking. It had been stored in his garage in Marblehead MA for a number of years. When I called Frank to have it sent back when he was done with it he told me he did all he could to make it look better (Mary did polishing work also). He said to me, "looks like it was stored in a garage on the East Coast." As usual he was dead on!
