Convert DAC to add FM

[Ruairi]

Hi I'm looking for an electricity-certified repair person to modify and add FM to my DAC 90A, since the BBC on LW will cease in a few days.  Grateful for any suggestions. Ruairi C

Hi,  
A DAC 90A is not perhaps the best set to convert to FM as its a live chassis with no transformer and has no low voltage supply to power the conversion.
It is possible, just not as easy as a set with an earthed chassis and transformer.
Do you have another set you could convert?
