I managed a few modifications during the Easter break, the case is now more or less as I want it - the front facia panel will be replaced with something more in keeping with the rest of the case ( veneered with traditional speaker cut outs ).
The focus control is the serrated knob, this allows me to go from a tiny but well defined image to a large less defined image - unfortunately at the moment this is a crude in and out rod arrangement - this will be replaced by a screw mechanism.
I will now concentrate on improve the quality of picture from the televisor ( any comments / tips would be welcome ) and to place the motor and brightness controlls remote from the unit onto the facia.
The Televisor unit is excellent and has given me the chance to re create
something that had been an enigma to me.
Thank you for all your support for my earlier post - all comments are apreciated.
