As posted previously the first build with the improved circuit is complete and sounding very fine indeed.
The resolution is improved compared with the previous build standard. Internal layout is thus:

Brief specification for MM version:
Passive RIAA, zero feedback.
Gain at 1kHz 40dB - Input 47k ohm, 80pF - Output impedance 200 ohms.
Supply from wall wart psu 12V at 1.2A
:)
