Hi everyone ,
An old t.r.f. has come across my bench. It looks as if it might be a homebuild or a kitset. All the valve sockets are held in with nuts and bolts, the holes for the sockets cut with a valve socket punch which has also been used to cut clearance for the venerable transformer. I am keen to date this set and have checked both "The N.Z. Radio Guide 1933 " and "The N.Z. Radio Guide 1934 " looking for circuits that use this set's valve lineup.The valves are 35 , 35, 24A ,47 and 80.The first three valves turn up in a lot of sets around that time but the 47 seems to have enjoyed only a brief "time in the sun".Does anyone have info on when this was?If I know this that will help me narrow my search.The set is not specially complex but sometimes its nice to find the circuit in an old publication to get a feel for what it was all about. Thanks all and cheers,
