Anyone try the Heritage Audio 1073 - 500 Series Mic Pre ??
What I have always read was that you couldn't build a true 1073 because the 16V - 500 Series Power Supply .
But I'm seeing an 1176 in the 500 series now , So do did Heritage really pull it off ?

Ahhhh.... that makes sense , splitting the power over 2 spaces for the AML 1073 . But with the Heritage Audio 1073 , looking at the back , it only uses one slot ?? |

There´s a lot of confusion on this subject... Your lunchbox´s power supply doesnt care about where the modules are plugged in ( phisically ), as all the slots power pins are electrically the same point. The power supply sees all the modules in paralell, applies Ohm´s law and delivers current ( and heats! ) accordingly ! Our 1073/500 is connected on just one slot, BUT leaves 2 more unmolested, so nothing else can draw current from them... Same result. Regarding the +-16v to 24v, there are so many ways of turning those 32v available into 24v, not a big deal. |

I have a pair of the AMLs. the designer worked for AMS Neve for several years before starting his own thing. They sound bananas

Exactly. Many folks continue to be confused about the API-like bipolar supply voltages. They think that the +/-16V supply as somehow being "lower" than the Neve-like 24V supply. The truth is that +/-16V gives you 32V to work with, and, as you mentioned, that can be turned into 24V no problem. There's nothing inherently superior about the Neve-like supply over the API approach. |

Ok , I get it now , thanks for explaining !
Really anything is possible for the 500 series , its just a matter of fitting all the components into a small space , which I would think would cause heat issues that would dry out caps and other problems more quickly than using the standard 19" 1U Rackmount .
I know where I learned the confusion about the 500 series power supply , it was on Gearslutz . People wanted a Neve mic pre for a long time and everyone would say the power supply was only 16V and couldn't run a Neve so stop dreaming .
Well Heritage Audio , your 1073 looks BAD ASS !!! The real Deal .

the issue is more that the +/-16V supply might not supply enough current. and also using a Voltage Converter can introduce noise if it's designed improperly. You can't really do tubes and properly feed them the Hi Voltage they need on 16V supplies. that's why the 51X DIY stuff was created, so you could have all of these modules. It's much better to use a voltage regulator to step down voltage, than a voltage converter to step up and potentially introduce noise.

There's nothing inherently superior about the Neve-like supply over the API approach. yes, the only diff between 51x capability and standard (24v, 16v respectively) is, it costs more money in parts/labor/space to bring up the voltage from 16v if i'm not mistaken. i would also venture to guess, u will run out of power on a standard 500 rack before its filled if using higher v single spacers |

I had the 1073-500...it was awesome...alas, I am poor and went to the jr...  |

I haven't really bought anything new in a while...Pretty settled on the Capi stuff, Helios (I did just buy that) and the Heritage...Also have the Brute. Don't really need anything else.
