• Annotazioni

• Delmonico International, a division of Thompson-Starrett Co., Inc., in 120-20 Roosevelt Avenue, Corona 66, New York imported at least chassis, perhaps the full radio from different companies. One was Körting-Radio in Germany. SAMS Photofact set 668, folder 4 from December 1963 shows for the same chassis/schematic the following Körting-Delmonico models: 931, 941, 951, 961, 981, 1091 and 1221. The models or the owner manual may also show a suffix - like 931A etc. The chassis are the German domestic Excello Stereo Chassis 24611 for music console 23661 - but at least the transformer (110-120 volts) and scale were changed for export. They receive "Long Wave" 150 to 360 kHz, Broadcast (Medium Wave) 515 to 1620 kHz, Short Waves 8.5 to 19.3 MHz and FM 88 - 108 MHz. They all have a record changer for 4 speeds and a stereo amplifier.
  
  The model 931 uses the tubes linked above. According to the owners manual, the 931A uses ECC85, ECH81, EBF89, ECL86, EM84, ECL86 and EZ80 plus two diodes OA172. The FM multiplex adapter uses two 2SB54 transistors and two RL232 diodes. There is a ferrite antenna, short wave bandspread tuning, compensated volume control, separate bass and treble controls etc.
