A development from the Decca Bradford colour chassis, the 30 Chassis utilises a vertical modular layout with easy to remove panels.
This model 30 chassis looks to be an early one, but unlike the model 10 which had a fully transistorised decoder and mechanical tuner, this one has the Motorola MC1327P integrated circuit which has lead to the RGB circuits being greatly simplified.
As was pointed out to me by Gary (405 fan) this set employs the Telefunken mechanical tuner which is reportedly one of the finest of its type. Extremely reliable and pretty much only needs a clean and lubricate to restore normal function if any drift is encountered.
