Harrison Laboratories 6204A D.C. Power Supply

Harrison Laboratories 6204A D.C. Power Supply
Harrison Labs became a division of Hewlett Packard in 1961, but I think they continued to use their own name on the supplies for a while thereafter. I don't know when they switched to branding their supplies as HP, but this one predates it. It was introduced in the 1963 HP catalog at a price of $99 plus an additional $20 for the meters.
