| Descrizione |
Sparks Withington (Sparton) used the name Viso-Glo for the Neon gas discharge tuning indicator VG-1. See there. This was in 1934/35. When in 1936 the first mag.Eye appeared, it immediately replaced the VG-1. But the name Viso-Glo was maintained for the 6E5. Sparton used it as a synonym for luminous tuning indicator.
Sparton´s Viso-Glo VG-1 was an ephemeral creature. It was already one year later superseded by the first real "magic eye" 6E5.
The VG-1 is found in the Canadian Sparton Models 467B and 580 as well as in the US models 104, 136 and 83. Sparton kept the name Viso-Glo for the 6E5. The list price for a VG-1 was $2.-, while a 6E5 was only $1.50!
There was no trace in the literature for more than 60 years, until an article was issued in the OVRC Newsletter, the bulletin of the Ottawa Vintage Radio Club, vol.8, No.4, Winter 2000. Authors: Gordon Symonds, Jim Berg, Ludwell Sibley and Lea Barker. But there is some misinterpretation. Please click above the "right designation", VG-1 to get our forum article from Konrad Birkner (April 2005), explaining how it works etc.
