SECTION 2




MAINS INPUT
This is very important and care and time spent examining this section of the radio is not wasted.

The most dangerous part of an AC radio, is the mains circuitry. Check this first before plugging it in. A common practice amongst radio collectors, is to cut off the mains cord or plug, immediately that a new radio is acquired. This method removes the temptation "to plug it in and see if it works", which can quite often ruin a radio with a loud bang.

Examine the mains cord, to see if the cable is safe, not perished, and no bare wires showing. Check for damage where it enters the plug and where it bends entering the chassis. Renew (or shorten) the cable if it is damaged. Use cable of the correct vintage. Use some rubber or cloth covered 3 wire cable from the junk box, or" figure eight" if the radio uses that type. An earth wire may not be required on these radios as they usually had a totally enclosed chassis and insulated knobs. Some hardware shops have "cotton covered" 3 wire mains cord for use on domestic clothes irons. This is suitable. Maroon coloured "cotton covered" mains cord may be available from vintage radio shops.

Examine the mains plug for cracks and bare wires, especially "whiskers", which may have escaped the wire holding screw.
Renew the plug, if it is cracked, burnt or dangerous, with a plug of the correct vintage.

Check the grommet or clamp on the chassis for wear or damage. Fix or renew it.

Check the ON/OFF switch with a multimeter to be sure that is is working and it has no short circuit to the chassis.

Check the power transformer connections.

Radios seldom have fuses, as they rely on the house fuse. Usually, this is all that is necessary.
