VDV-2100-CFB-PPS

Description:
(Previous number PAT-4006-CFB).
The very wide bandwidth (220 kHz) toroidal push-pull output transformer 2100-CFB-PPS is meant for very high power (100 Watt) extreme loud high-end tube amplifiers. Four paralleled power tubes (6550, KT88 to KT150) should be used for high-end applications. Separate cathode feedback windings of 10 % plus 33 % UL-taps create extreme low tube distortions with high speaker damping factor without using any overall negative feedback. The primary impedance is close to 2 kOhm. The secondary is at the standardized 5 Ohm impedance. This transformer is meant for clean dynamic high quality sound reproduction. The transformer is fully potted in an attractive aluminum black textured shell.
