The Bush DAC90 was the predecessor to the much improved DAC90A. . As can be seen from the chassis photo below, the large dropper resistor is housed in a metal shroud on the right. The heat produced by the dropper usually burns a large hole in the back panel, however, It is possible to repair the back panel to make the radio safe.
This photo shows the chassis from the rear of the radio. There are no user serviceable parts in any valve radio, and the Bush DAC90 is no exception. In fact, like many vintage radios, these have a live chassis so disconnect the radio from the mains before removing the back cover. Better still, do not remove the back cover.
