Default Re: Regarding home made TRF

Neil, I did say I could be wrong! I found a more comprehensive datasheet which suggests the 3.9K is a little low (4.7K or perhaps 5.6K depending on HT) not as much as I had thought - it will be running at <1mA anode current. As mentioned above the gain is 15 whilst the EBC33 acheives 23.
