notes: label: Description (Brief)
content: An AudioTron tube mounted in an adapter. Tube: Double-ended glass tube with insulated leads emerging from both ends, no base. Cylindrical envelope. Adapter: metal shell with vertical supports, 4-pin "Shaw" base. Donor card reads: "Adapter made just after World War 1 when patent conditions frequently made late models of tubes unavailable. There was an ample supply of pre-war AudioTrons and De Forest Model T tubes around most amateur stations but the post-war [devices] were all equipped with the "Shaw" type sockets [making adapters necessary]. A very efficient AudioTron tube is here mounted in an adapter [to be] inserted into the Shaw-type socket."
