AMPHF - Heathkit SB-220 Heathkit SB-220 liner amplifier. Matched Eimac 3-500z full output tubes, properly grounded grid configuration, soft key module for late model radio protection, MOV's installed for line surge protection, upgraded filter capacitors and diodes, upgraded metering circuit, glitch protection resistor, upgraded parasitic suppressors, upgraded T/R relay for fast and quiet switching for superior vox operation with none of the open-frame relay clunking, soft start upgrade for inrush protection, LED meter lamps for crisp and bright backlighting (incandescent bulbs will be provided if you prefer that). The case and face are nearly perfect. Currently set for 240v. This amplifier needs nothing. More pictures are available. I will NOT ship this, but willing to drive a considerable distance to meet or you can come here. If you arrange shipping and packing, I'll deliver to a reputable shipper here. $1250 Listing #1734190 by KY7X Submitted on 06/26/25 Submitted from 50-37-26-237.grdv.nv.frontiernet.net Click to Contact Back to Previous Page
