It came with a couple sets of coils, a bandset coil set for 80 metres and an unknown coil set that was hand-wound by a previous owner as well as two sets of empty coil forms for my own hand-wound coils. Subsequently, I have obtained a bandset coil set for 160 metres.
I am now looking for a period power supply, preferably one of the National "Dog-House" power supplies.
My SW-3 is one of the earlier version 2 receivers. It has a pair of 58 valves (tubes) and a 50 valve (tube). The filaments are 2.5 volt and the B+ is anything upwards of 350 volts though the National power supplies typically supply around 135 volts. Meanwhile, I plan to locate a nice high voltage lab supply to be able to test this little beast out.
