Got an interesting 1920s set yesterday.
Nameplate says IVEYLINE//Manufactured By// The Southern Toy Company// Hickory, NC
The tube lineup from left to right is: UX199, X171A, MU20, MU20, CX300
The X171 is a Gold Seal tube, and the UX199 is in an adapter which in turn is mounted in the socket.
Unfamiliar with the MU-20 tube. One of them has on it's base Davin Amplifier//Type MU-20// Fil Volts 6// Fil Amps 1/4
