Default Re: My attempt at a TRF

Hi Adi,
I put the transformer and bits in the post this morning. I think you may get a better result with the transformer fitted in place of the earpiece. Try leaving the 100K in place and connect your earpiece from the anode via a small cap say .047 to chassis. Maybe a glance at your circuit will be useful for further information. Your R.F. stage is not recommended at the moment. The one valve detector should give a good result on its own. Your coil should also be o.k. even if its a bit distorted. Keep us informed!
Regards. JOHN.
