Easy upgrade for the Drake AC4 power supply  Time owned: 0 to 3 months
This upgrade kit for the Drake power supplies comes as assembled boards. Installation is relatively simple and doesn't require building the board from a kit. This eliminates at least one source for errors. Takes about 6 hours if you are taking your time. Consists of two boards that mount using existing holes in the chassis and is easier to fit in the chassis than some other options. Completely eliminated the 60 Hz hum in my TR-4 and insures operation for many more years. 
Product is in production.
