Used to be a Yaqin CD2 vacuum tube buffer--this was a brand new unit that I gutted. All point to point wiring, all new caps--larger Nichicons in the PS, and WIMA MK series for signal path. Additional WIMA bypass caps added in critical locations. Junk chinese tubes replaced with a matched pair of NOS GE JAN5654W mil-spec tubes. Aluminum panels and obnoxious blue LEDs replaced with hand-finished real oak wood panels and a single red LED power-on indicator on front panel, and a single LED recessed between the tubes for night illumination. Now it looks and sounds like it should!--$175
