12 July 2021: Due to a flood at my home/shop, Harbach Electronics is closed until I get this mess cleaned up and all of the damage repaired. Effective immediately I will be closed how ever long it takes to clean up and repair the damage. All pending orders will be canceled and refunded via the method of payment. I am sorry for the closure but I have to get things repaired and cleaned up. I hope to be back open around mid-October 2021.
You can still view products, but no orders are being taken at this time. Sorry for the inconvenience!

SKU: SK220 Category:

Description

The SK-220 safely acts as an amplifier interface to your modern transceiver to the Heathkit SB-220 or SB-221. This unit is mounted inside the amplifier and transforms the 120VDC key closure to approximately 0.7VDC at 1.5mA.  Without it you run the risk of severely damaging the keying circuit in your transceiver.
