Audiophile, DIY F4 solid state 25W on 8 ohms amplifier - $1,100 - (Norwalk, CT)

Hello, This is a well built, DIY First Watt F4 clone. The F4 is a unity gain ( buffer ) amp and needs a high gain preamplifier to reach max power of 25W on 8 ohms. I used high quality components for a long lasting amp. See pictures that tell the story. I've used the amp for maybe 50 hours in total. It works in synergy with full range driver speakers 90dB an up. It is biased so it works class A at full power. I love to use it with my full gain DHT preamps. Some of the components to be noticed are the medical grade Triad toroidal, ultra-fast rectifiers, Nichicon KG filtering caps of 60mF per rail, Elna Silmic II in the signal path. I built it at the end of the last year to keep. However, I need to sell in order to finance other projects.
