Description:
The 4070-CFB-PPS output transformer has, besides Ultra Linear taps at 33%, extra windings for 7.1% cathode feedback. These local feedbacks combined create a low impedance drive of this transformer, resulting in a 70 Watt power bandwidth from 14 Hz up to 200 kHz and lowest transformer distortion. With 6550 and KT88 tubes high quality low distortion sound reproduction is achieved while micro details are well amplified, without further losses. The primary impedance is 4 kOhm with a standardized 5 Ohm secondary. See download application for a description of a special amplifier with this transformer. The transformer is fully potted in an attractive aluminum black textured shell.
