Re: Decca Bradford Preset Brightness Modification?
As with all long-ish production runs (except for the Pye hybrid) there were lots of improvements along the way, such as a spring-fusible resistor instead of the unreliable fuse in the HT feed to the line stage. I think the last versions (the 33 chassis) had a resettable 'red button' cutout in the feed. These black-fronted 22" sets gave a fine picture, though perhaps the discrete decoder in the10 chassis had the edge.
