Re: Baird Garrick
Hi all,
I have attached some pictures to show the changes made to the line timbase.
The first picture shows the modified circuit that the set had when I received it. Note that it has flyback EHT. The transformer was a bad match with too much output and severe distortion to the right hand side of the picture. An inductor had been placed in series with the line coils to reduce the width (relative to the EHT).
The second picture shows the corrected circuit as originally designed.
The third picture shows some of the detritus that was removed. At this point I had already replaced the 1K width control for one with the correct 2K resistance.
The fourth picture shows a 50uF capacitor of the correct type for the line scan coil coupling in this set. It has been re-stuffed.
The fifth picture shows a round cover that I made up to cover the rather unsightly hole (it was roughly cut) that was left after the extra line linearity control was removed.
Cheers
Andy
