VDV-2100-PP (PAT4006)

Description:
The very wide bandwidth (300 kHz) toroidal push-pull output transformer 2100 is meant for very high power (100 Watt) extreme loud high quality tube amplifiers. Four paralleled power tubes should be used like the EL34 (guitar) or the 6550 or KT88/90 for high-end applications. Screen grid taps at 40 % are present and the primary impedance is close to 2 kOhm. The secondary is at the standardized 5 Ohm impedance. This transformer is meant for very loud and dynamic high quality sound reproduction with bas-reflex or closed box loudspeakers. Larger than normal ratios of overall negative feedback are allowed, while resonances are absent. The transformer is fully potted in an attractive aluminum black textured shell.
