Still consider the EL-506 Sharp Calculator the best calculator for scientific work!!
My first Sharp EL-506 purchased in the early 1980's and is still fully functional. Bought this new in the package vintage EL-506 to use for a backup is the first one ever fails. I use the first one extensively to this day. I sincerely wish that the EL-506 would be remanufactured again as this calculator has no peer especially for the money. Good instruction manual too! It has storage features not found on much more expensive calculators.
I consider myself fortunate to find this vintage new in the box replacement!!!

Broken
The amplifier suffered considerable damage in transit to my residence. Broken plate coil, rf choke, bypass capacitors, one 811A tube cap broken letting air in tube. The shipping route had more than a half dozen stops from New York to Medford Oregon. The package suffered blunt force trauma that caused the frame to be bent on both sides end to end. I cannot rate the amplifier since it is non-functional at this time. I am hoping I can repair it to working order.
