TRF Receiver

[BusyBee]

This is where my lack of experience is showing, as I am pretty unfamiliar with any of the valve sets which used ferrite rods although I have occasionally come across them. From the general information I have found it looks like TRF sets would be rare or even non-existant by the time ferrite rods became commonplace in commercial radio.
