Note 1 : Service data suggests there were models 4836F and 4836R ;
presumably 'F' and 'R' refer to "Front" and "Rear" projection.

Went on to form part of the company "G. D. Developments" who advertised models 2015, 2418, 4836F and 4836R.

NOTES : The 2015 and the 2148/4836R/4836F mainly use the above schematic.
The main differences seem to be in the RF generator used to generate the
25KV for the projection tube. You can find more on the E.H.T generator used
on projection sets in the Telly Techie section, although some White Ibbotson
sets seemed to have used parallel valves driving the E.H.T transformer.
