BREAD BOARD 6 VALVE RECEIVER, 1930's

Many small companies sprung up in the 1920's making wireless sets for sale. These unfortunately soon suffered from the large companies going into mass production and flooding the market. This receiver has six valves four of which are RF amplifiers, Long Medium and Short wave making it ambitious, as Superhetrodynes had not yet become widely available,so much amplification must have produced a lot of unwanted noise. A label on the set says Made by J.Karslake & Son 264 High street, opposite the Post Office. Exeter 2510.
The coils inside are Wearite types, carefully matched for three stages of a TRF or "straight" receiver
The cans are copper and the coils plug into standard B4 valve sockets.
The covers were vital for a stable receiver so that there was no unwanted coupling between the amplifying stages.
