radionette: Earlier version - different tubes
I found earlier version of this radio, equipped with tubes: DK32 DF91 DAF91 DL94, serial number 349319. Photo of chassis and schematic attached
Use the Create New Model link on home page. It's sufficiently different to need a new page.
See this model that has three other model pages. The maker called all of them "T" and they all look the same, except some early TA2A models have a 1.5V scale lamp and button. The same basic chassis and circuit was used with different tube line ups on maybe 11 modes/versions from 1949 to 1962!
All-dry Transportable Receiver Model T [TA2A]
The four versions use incompatible tubes but identical cabinets. Later versions may omit the scale lamps.
- TA2A DK91 DF91 DAF91 DL92 (This model). Only the early TA2A versions have the scale lamps.
- TB2A DK91 DF91 DAF91 DL94 Intermediate versions, various revisions
- TC2A DK92 DF91 DAF91 DL94 Last 250mA Transportable T (entirely same pin wiring as DK96, DF96, DAF96 and DL96) From Serial No. 544750 all revisions are included.
- T S.Q. final production before Sky Prince using using DK96 DF96 DAF96 DL96. Early version of Sky Queen chassis does seem to use same component values as TC2A above S/N T 544750, so may be simply a valve change.
