       Emerson Wondergram.   Portable battery Turntable. Produced from 1960 to 1965 by "Baird", England. Allows you to listen to records at speeds of 33 and 45 rpm. Dimensions 220 x 110 x 50 mm Weight without batteries 850 g, nutrition 6 v, the four-cell battery C. Structurally, the apparatus is designed as a bakelite case, in which the top is inserted a metal deck, which is mounted all the mechanics and electronics. Lattice dynamics is below, and for better hearing on the case, there are three Turndown legs. Mechanics fairly tech and high quality. The design uses molded components.
     When you open the lid lock tonearm is released, and it rear its on deck with a special spring mechanism. To activate electrophonic should simply withdraw the tonearm from the starting position to the side. Circuit
collected on the three germanium transistors type GET114 (1 pc.) And S1 (2 pcs.) Manufactured by General Electric Company, and two transformers. There is volume control. Pickup piezoceramic has two needles. Inserting a pickup in the holder properly, you can choose what kind of needle to use. The plate is installed on a freely rotating stand, not connected with the engine. Rotation of the plate by means of two rollers protruding from the deck at different distances from the center. These rollers protrude from the deck at different heights. Thus, if you have disc "45s" small diameter, it rotates the roller is located closer to the center at a speed of 45 rpm. If a disc of large diameter, it rotates a distant spot, rising from the deck to a higher altitude than the closest. In this case, the disc rotates at a speed of 33 rpm. Also on deck and on the lid are supporting rollers that keep the disc rotating in the correct position. To play "45s" having a large diameter hole nozzle provides for the storage of which is a special place on the inside of the lid, beside with the auxiliary roller. In the closed position the cover captures the latch with a button.

      The device was bought complete with a leather cover, in good cosmetic condition, but a failure. Mechanics was in order, all the commercials intact, and required only the replacement of lubricant. Electronics not working, and needed replacement of all three electrolytes, and repair of AC resistance of the volume. The design of the variable resistor is not provided for repair, but was no alternative, had to file down the rivet on both sides, restore contact engine and fasten all screws. At present, the unit is in working condition. The sound quality is decent, I assumed that would be much worse. Volume also missing.

     During the renovation had to replace all the electrolytic capacitors. To retain the original form design, I made out the old capacitors, removed the aluminum liner interior, and put them in the new capacitors are suitable denomination and size. After assembling the capacitors were obtained very similar to the original. On the left the original capacitors. Right - the new ones.
