I cant recall how big they were exactly but around 6-8". The entire TV ran on 10V, when using the 12VDC supply it first passed through a 10V linear regulator, when using on 240VAC just used a 12V transformer then through the same reg. The most unreliable part of them was the regulator and a switchmode equivlent of the genuine encapsulated part used to be available from GB telespares. That said I do recall one time having one of these chassis fail to fire up the horizontal and it did turn out to be the jungle / sync IC. Regards James
