I have an RGD radiogram that has undergone considerable modification to the amplifier. I wanted to be able to use it to provide as good a quality sound as was reasonably possible, whilst still keeping the electronics in tune with the period (1953). It is not one of the more valuable or rare types, otherwise it would have been kept original. However, I use it regularly and get much enjoyment from it.
It was in a bit of a state when I got it, the original output transformer was open circuit on the primary so that was my excuse to try and improve....
