I NOW ONLY REPAIR BUSH VALVE RADIOS FROM THE 1940s AND EARLY 50s
WHAT A FULL SERVICE MEANS
This is what I will do when I service your radio. Obviously, I locate and repair the fault. But that’s not all a service involves. Check the list below for the full procedure.
Dismantle the radio, clean the chassis and interior of cabinet.
Locate and repair the main fault.
Replace all wax coupling and decoupling capacitors.
Replace mains filter and aerial isolating capacitors using Class X or Class Y capacitors for safety reasons.
Check all resistors for signs of burning or deterioration.
Replace electrolytic capacitors where necessary.
Check all rubber grommets and tuning gang mounts and replace where necessary.
Check internal wiring and replace where necessary.
Check earth tags and connections and tighten where necessary.
Check connections to, and safety of, the mains dropper if applicable.
Replace dial lamp bulbs if blackened or blown.
Replace dial drive cord if worn or broken.
Clean and lubricate dial drive pulleys, tuning capacitor bearings, all switches, potentiometers and valve bases.
Test and replace valves as required.
Carry out full oscillator, RF & IF alignment using test equipment.
Check loudspeaker for cone damage and sound quality.
Fit new mains lead and plug if not up to British Standard.
Megger test insulation on mains transformer (where fitted).
Clean and polish cabinet and knobs etc.
Soak test for several days.
WHICH RADIO STATIONS WILL YOU BE ABLE TO RECEIVE?
There are some stations which don’t transmit on long or medium wave. Before you have your radio restored, learn more here.
IMPORTANT SAFETY NOTICE
Some radios have two pins on the rear for the mains plug, such as the Bush DAC90 and DAC90A. I will disconnect and insulate the two pins and fit a new mains lead directly to the radio, unless specifically asked not to by the customer. I will leave the two pins in place so as not to devalue the radio.
All this is included in my normal service procedure and won’t cost you extra, apart from the components fitted to your radio.
If you simply want a quick fix, like a faulty valve changed, rather than a full service, that’s not a problem. Either way, it won’t cost you a small fortune.
