Has a flat, rimmed metal base and a low front panel with 2 pairs of power rails and a tall, angled rack with 4 pairs of power rails extending horizontally. On the base, there is a power supply with a transformer and a full-wave rectifier. The front panel includes an off/on switch, a light to indicate when ON, an ammeter presumed to indicate the total current drawn from the power supply and an unconnected rotary telephone dial on the right. On the (power) rails, there are several different kinds of component board each with one Terry clip on the top and two Terry clips on the bottom holding them to the rails. There are also assorted multi-coloured interconnecting leads with 1 mm plugs on either end between some of the boards. Boards: 5 rotary switch units; 16 "914 GTS"'s; 2 "903 GT"'s; 15 "926 JK"'s; 3 "927 INV"'s; 6 D-units; 2 "904 H/AD"; 3 "PB" press-button switches; 3 "RS" press-button switches; 3 SW silver toggle switches. Has a painted logo "Elektrokit" on the top bar of the rack. Yellowed paper labels on crossbar of rack denoting columns 0 through 10. The 926 JK's have operational amplifier "SGS F 5992629 6637" with 9-pin integrated circuit. A 35 mm slide among those donated to the collection by Wallace Bell (ABDNP:201981a) shows a device presumed to be this item in the Department of Engineering at Marischal College in the late 1960s. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1965-1970 | Source: | University of Aberdeen | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
