I need your help... 'Amp Camp Amp' to listen to my records without a pre-amp.
My question: Can you directly connect a 'Pro-Ject Phono Box MM' [~Vout: 500mV/1 kHz at 5mV/1 kHz]
to a Rega P-6 with 'Exact 2 MM' [reqs: 7mv, 47k ohm, 100pf]

Yes.
You may have enough gain for your speakers without a line stage, it depends. The amp has 14 dB (x5) gain.
But you also need a volume control before the amplifier. An example of a passive volume control:

If you need more line level gain than 0dB, and you may, then you need an active line stage with gain (a preamp).
So instead of the above passive product, get a different one with line stage gain, perhaps 10dB to 20dB.

Passive volume control like schiit sys is not a good idea infront of aca, because it will change feedback.
Better use b1 buffer.

adason, good to know... so it would have to be an temp purchase of a 'SAGA S+ or the b1 buffer. I will investigate the b1 buffer first.
The PCB and matched JFETs for a B1 buffer can be bought together from the PASS DIY store. The B1 Korg Nutube chassis can be modified to mount this PCB pretty easily, you just need four new drill holes in the bottom plate. You'll need a volume pot (the PCB adapter for it is nice but not essential), RCA jacks, power & source switches, & the rest of the BOM.
