Transistor datasheets Russian Germanium

I checked the datasheets to make sure I was right in my last post. The transistors I've been (MP40) using are rated 1MHz. The P416 is rated 40 MHz. They said a TRF with 1 RF and 2 AF stages was as good as a regenerative with 2 AF stages. Maybe a P416 RF stage is in order?

How many stages should a receiver have?

I posted a link to the book in April 2017.
