Re: Sony 9-90 Width Control?
Hi Peter,
There's no width control. I attach the relevant part of the circuit, in case others would like to muse on how one could be added.
I wanted to reduce the width on mine about 40 years ago and I seem to remember I resorted to reducing the 12v power voltage by a volt or so... not ideal. Presumably Sony set the width so it would still be reasonably sufficient even on a partly discharged battery pack.
