VTL5C1 vactrols for use in amplifiers, effect pedals, synthesizers and more. The VTL5C1 was commonly used for channel switching circuits in amps made by Crate and others.

High quality vactrols from Xvive. The Xvive vactrols are clones of the original Excelitas / Perkins-Elmer vactrols used in many effects pedals, synthesizers, compressors and other equipment. These vactrols feature a thick epoxy sealed casing. The VTL5C3 and VTL5C3/2 both have a steep slope, good dynamic range, a very low temperature coefficient of resistance, and a small light history memory.
