"Dolce" - Pass inspired Class A amplifier

 












After building a very expensive F5 Turbo for another I thought I would build my own. Using Jim's Audio F5 boards, a cool looking 200 X 300 X 100 enclosure a local 160VAC tranni and  4 X 10,000uf caps I built this. Looks cool sounds even better. 

I didn't push the bias current so the amp just runs warm and the sound is the same - "warm". The name "Dolce" really says it all. The upper bass is rich and fills the lower mids giving male voice extra weight and chest. The woofers bloom a bit more and bass goes down to 30hZ in my system. I like it and so does the new owner.
