Greetings Edward:
I do all my own restorations. When it comes to anything electronic, the first thing you need to know is the model number and serial number. From that you can get to step 2, finding a schematic diagram. I would recommend Peter Wall in San Francisco but he is a long way from you. There must be someone in your area who will do the restoration but likely any professional will charge a hefty fee. The model and serial are likely put on the back of the cabinet or on a plaque attached to the radio or amplifier chassis. Andrew is quite correct about the capacitors being dead. The speakers of that era used the field coil for a choke (inductor) to smooth out the rectified DC in the power supply so when the caps are dead you get 60Hz hum coming from the speaker. You really should never apply full operating current to any old TV or Radio that hasn't worked in years. Bad things can happen quickly to delicate components. Shops specializing in old electronics often have Photofacts or Wiley's service bulletins. Again this starts with the model number. Lastly, don't go poking around when the unit is powered up. Some units like my Edison C2 have HOT potentiometer shafts. I can tell you that to have a few hundred volts surge through your body is no fun. These old units are best safely brought up in line voltage slowly with a variac and made more safe with an isolation transformer.
