Hi,
These are great diy radios !
This is something I miss in the Lectron set : a transformer with center tap. So many inductive experiments can be performed with these and they are ideal for coupling transistor stages.
Have you also checked my is ill at or circuits ?
I made use of the high tension transformer of the Base kit .
As amplifier for your radio maybe the legacy preamplifier block could also be used.
Greetings
