Bush DAC70 is an a.c/d.c mains valve radio. It was made in 1958, and has the
same cabinet as the model VHF90A radio. It has long and medium wave reception.
The valves used in this receiver are:-
UCH81, UF89, UBC81, UL84, UY85.
This receiver has many "Hunts Mould seal" plastic coated capacitors in circuit. These should be replaced with modern equivalent capacitors. There are a number of resistors that also can be a problem - replace also!
The dial illumination (240v @ 15w pygmy lamp) is a bit too powerful for the receiver, it is more suitable for a larger radio. It can burn the scale if it is not placed in its correct position.
I used a 10w type in my receiver, it gave somewhat adequate illumination but did not illuminate the whole circular dial, but nor did it scorch it either!
Maybe Bush tried to make up for the lack of illumination that they had in their early DAC90A, & DAC10 radios?
The "piping" around the edges of the speaker cloth is missing on my example. I may get around to buying some later. It may add a bit more cosmetic appearance to the radio.
