Description :
The Vintage High Power is a wideband low-feedback monoblock power amplifier producing approximately 100 watts per chassis. It is largely based on the legendary Williamson circuit, which was first published in England in 1947, and was the mainstay of the original high fidelity movement. It uses KT88 tubes.
In the refined form presented in the VAC, this circuit delivers true state-of-the-artperformance, and repudiates the more complex designs seen even to this day. The output stage features independent cathode bias for each tube, which results in excellent sound and the most stable and maintenance free operation available anywhere.
