AP EVO FFX
A grander open architecture type chassis, which allow us to expand our design technique. For the phono stage , the bigger size allow us to add more parts and using IC chip to be even quieter. As for the linestage, we kept it minimal-best approach with the WE396a did most of the gain and where as the CV181 for cathode follower and matching impedance. We also redesign the layout for bigger caps. However, the show stopper is at the power supply - takes almost half of the chassis, where we adapted either a 45 or 2A3 as power supplies with a choke transformer filtering it under the surface for quiet operations, and a NOS-6SH7 (was thinking EF86) for regulation. And the rectifier stage has many options as the Hashimoto proprietary power transformer has 3A provided many types of rectifier tubes for sound tuning. There is a second Hashimoto proprietary small choke transformer as optional for the AP FFX too for the perfectionist golden ears. It’s extra especially we already have 3 oversized ECAPs in the service. For the AC Inlet, we finish it with Furutech’s FI03 Gold to voice the preamplifier.
