• Remarques
• The Wurlitzer Model 600 existed in three different variations: 600K with a horizontal row of metal keys to select. 600R with a circular array of red plastic buttons to select. 600A which had a more elaborate coin mechanism capable of rejecting fake coins. The rejects were dropped into a cup located on the lower right front corner (similar to model 24-A). This coin system was required in "bad" areas where the clientele might try to use fake coins.

  Details seen in photos: The cylindrical white and silver object hanging below the record stack is a popularity meter, which tells the operator of the jukebox how many times each record was played. He can then remove worn-out records and those records that were not popular.

  The little silver box on the left side below the volume control box is a Kit 87 Wurlitzer "one tube (6J5) pre-amplifier" to give better volume for wall speakers and large rooms. With it, the sound system has an extra stage of amplification and 6 tubes instead of 5.

  Notice the significant differences between this jukebox and the incorrect one we show too as model "600 Jukebox-mix-up": 24-play mechanism, motor, proper (smaller) amplifier, proper electrodynamic speaker sitting on floor, etc.

  About 10,000 Model 600 jukeboxes were sold, in all configurations. The keyboard model is the most common.

  Wurlitzer amplifiers of this era had a unique "Quick Start" feature: In standby the tube filaments are not heated. After a coin is inserted and a selector button pressed the tube filaments are supplied with 9.8 volts for rapid heating. A relay time delay will switch to normal supply (6.3 volts) after about 7 seconds. That makes the Amplifier ready before the pickup is set into the record groove, since the player mechanism needs this amount of time to place the record into playing position.
