Albert<\/a> sent me recently some great pictures and feedback of his 26 pre-amplifier using\u00a0gyrator as the anode load similar to my design on the 26\/01a<\/a>.<\/p>\n

\"DSCN0734\"<\/a> \"DSCN0742\"<\/a>Here are Albert’s notes on his 26 preamp:<\/p>\n

“I have my 326 with separated power supply, 5U4G – 8uf PIO – 20H – 50 ASC – 30H – 50 ASC + 18uf pp feeding the \u00a0Salas’ HV Shunt V2 Regulator, then to 2 ( left and right ) cascoded DN2540 gyrators. Rod’s filament supply coupled with filament bias @ 850mA with anode @135v. I don’t have anything to check the distortion, but this is the most good sound preamp that I have finished to date. It pleases my ears so much that I have the intention to turn it on once I’m in the house. It sounds gorgerous with very good image seperation. Sound stages are wide, deep and absolute quiet.\u00a0The highs are sparkling smooth with lots of details. Mids are lush and warm with admirable vocals. I’ve found it even better at the lows if compare with 2x 156c. It goes deeper with clear notes.”<\/p>\n
