SS-221-120 Soft-Start Module
The SS-221 limits inrush current during amplifier start-up by placing a small resistive load in series with the AC mains. The load is switched out of the circuit by the relays a few milliseconds later. The soft-start mounts inside the amplifier and safely limits inrush current to protect hard-to-find and costly-to-replace ON-OFF switches, tubes, filter capacitors and high voltage transformers. The kit is for SB-220/221 amplifiers operating from 120 VAC mains and includes power resistors for 120VAC mains operation (10Ω 10 watt).
