Description

The Arcturus metal glass type 58 tube is unusual in that it employs a glass disc instead of a conventional "pinch" for introducing the lead-in wires into the glass bulb. The disc has the wires in a circular formation. The base is octal but an adaptor was sold with the tube to enable it to be fit the normal U6A 6 pin tube socket. The adaptor measures 37 mm long and is 30 mm diameter.
