Heathkit SB-220/SB-221 Heavy Duty Power Supply Bundle Upgrade

Description: This is a rectifier/metering/filter capacitor bundle for the SB220/ SB221 amplifier. It uses OEM wiring but does the following: 1.) Uses better longer-life capacitors and bleeders than any other board2.) Opens the capacitors up for better airflow. Cooler capacitors mean longer life3.) Adds a 10 ohm 10kV rated surge/fault limiting resistor. This is an actual 10kV-rated part, not a low-voltage part4.) Converts metering and other components to standard components5.) Increases the headroom on all systems6.) Fully protects the meters from tube and other shorts7.) Allow adaptation to other meter systems but works perfectly with OEM meters8.) Moves bias on board with real Zener diodes9.) Adds rail clamp diodes10.) Retains Heathkit wiring. If you have missing or damaged wiring please let us know before ordering These units are fully assembled and tested. They are not raw parts. The components and boards meet commercial design standards. Instructions are at https://www.ctrengineeringinc.com/download-files-page/ In addition, we have tens of thousands of other RF and analog parts, tubes, and kits. We have been an OEM RF system design business for half a century, spanning vacuum tubes through LDMOS.
