Verified this last night. Here's a pic of my build.
Used some Russian мп38 germanium transistors (Q1: 80 hfe Q2: 110 hfe) and a 7.5k resistor in place of the 10k trimmer (ran out of those). For the input cap I tried out a couple different values (47n, 100n, 220n...) but settled on 39n, as it seemed to give more clarity that higher values. Socket and experiment.
