Default Re: Marconi 702. Sound problems.

Pictures of the power supply unit as fitted in Marconi 702 and HMV 901 vision only TV receivers.
This unit must weight almost as much as a modern CRT mono TV set, I estimate it weights 15KG. It's not an easy unit to remove from the cabinet. There is a box assembly on the underside of the chassis which is positioned below the floor level of the cabinet so this heavy power unit has first to be lifted up to be clear the rear cabinet batten.
These sets might be fun for TV enthusiasts and collectors but as Peter says in the 1950s most service engineers would be glad to be shot of these monsters.
