Quote from Radio Museum
"They (RGD) were taken over by Regentone in 1952 but the R.G.D. brand name continued.
Around 1960/61 STC took over Ace, Argosy, Regentone and RGD. Marketing and distribution moved to the KB Factory in Footscray, Kent. Eventually the radios were made in the Far East, as were ITT KB. In the early to mid 70's the names RGD, Regentone and KB were all phased out and radios were sold in the UK as just "ITT". "
It looks like the RGD models and Regentone models were closely following each other following the take over of RGD by Regentone, but there does not seem to be a lot of influence from KB.
As far as I can see KB radios started to share the same chassis as the Regentone and RGD brands from about 1963, a year or so after STC's take over of the RGD/Regentone brands
I am pretty sure the RGD B56A shares the same chassis and circuit as the Regentone BT11.
There were quite a few radio models from both RGD and Regentone which used this chassis with the "potted resistor modules". I may be wrong, I am only going from my own collection, but I dont think there are any KB radios with this method of construction.
There is available a Trader sheet for the BT11 on P Stennings CD, and that has the voltages associated with the transistors, so I could if I wanted attempt further repairs.
