Re: Gec bt1091.
I've refitted the cabinet and the set will be taken off the bench later today.
The picture is a lot better now. The focus control is a 500 ohm variable resistor wired across the focus coil. To improve focus a 680 ohm resistor has been added in series with the control, later on a 1Kohm pot will replace the focus control presently fitted. The line linearity needs attending to but the original width and linearity controls had long ago gone faulty and replaced with fixed resistors. The truth is this is a horrible example of what is not one of the nicest sets made by GEC Radio and Television Ltd. And you think this set is not very nice, upstairs there is a GEC BT7092 9" console TV set which was made two years before the BT1091. BT7092 has mains EHT! DFWB. |

I missed out on getting the wooden 'bookshelf' version a while back, now that was quite an ugly set! I am looking forward to getting started on some of my sets once I have regained use of my right hand again. Mark |
