Likely the Easy Built Super 5 circuit from the start of the Lamphouse Kitset Review.

Power transformer, R03, Beacon (280-0-280@60mA, 6.3V@2A, 5V@2A*)

Choke, C03, Beacon, 10Hy, 60mA, 400 ohms

IF transformers, type 242, Inductance Specialists - 455Kc/s

Aerial and Oscillator coils - unshielded Inductance Specialist types

*The power transformer used was likely designed for an 80, or 5Y3 as it has a 5V rectifier winding.  The 6X4 used in the circuit would have worked, just slightly less efficiently.  It seems to be this way in the Lamphouse kitset design - possibly the R03 transformer was cheap now that 6.3V rectifiers were commonplace and the more commonly needed transformer would have 2 x 6.3V windings.
