Hello Ron ….
A very belated reply only to say I did buy one of your PH-3D units 2 months or so ago, from your NZ agent. Very pleased with it. Easy to adjust load/gain settings, gain is more or less enough, but a higher 65 would’ve been more desirable for my purposes, running a Benz Glider 1.4mv MC cartridge now. All sounds good, quiet, yet dynamic really does everything so well.
A great unit, congratulations, so keep up the excellent work.
