Found some new ON Semi 2N3904 ordered a few months ago.
New schematic in:
Using common part values.
Very close to Zin = 50 Ohm.
Moved output to mid Vcc, which increased gain some.
Visible oscilloscope clipping at about 17 mVrms input, 5.48 VPP output.
Assuming a 10-15 VDC field friendly rig with 8V regulated rail.
