Yes, of course. Electrically, it's exactly the same result as using a passive preamplifier. You've just moved the volume control from a separate box into the phono stage chassis.

Just keep in mind that depending on your gear and setup, you mind need a buffer after it

Instead of using big oversized bridge rectifiers, why not try using two of them and form a better power supply?

You will need two separate secondary windings for this one.

Other than moving the filter capacitors from the power supply to the phono boards, that's what we have already.

Just completed my phonoclone last week and after couple of days run in, it's absolutely freaking awesome. It ate my heavily modified dynavector p75 for breakfast lunch dinner supper and what have you and this is not even a dual mono configuration yet. Mind you my p75 was running using a dual rails linear psu and had the internal SMPS bypassed.

Thanks for much Richard for the product!

Give it a couple of weeks more for the caps to break in and you are in for a very nice treat

The caps I used were already run in... So pretty much about there. Now I am contemplating better output caps. Now using some Mundorf MKPs.

I changed the output caps on my PC3 to ClarityCaps

A no brainer upgrade IMHO

The PC3 blew my P75 away as well.
