Group Buy - Golden Reference HV/LV

[sorenb]

Group buy from PCBNet (same as Carbon and Circlotron Group Buy) for boards > 40.

 

State your interest here

A table and a modular graphic for easier overview of the various Golden Reference PSU boards and their function:

The color scheme is the same used in the modular picture below.

 

Options, each representing a full PSU everything needed for an amp (in the spreadsheet one can choose either):
Option 1: Contains HV+/-, LV+/- and PRO BIAS.
Option 2: As Option 1, but “Split” into two separate boards, making mounting more versatile. (Skinny and FAT contains the same, but Skinny is rectangular shape wheres FAT is sqarish)
Option 3: Separate boards for each HV rail, LV rail and BIAS board (containing both PRO and NB BIAS), a total of five boards, and chassie mount caps.
Option 4: ONLY low voltage - contains the Golden Reference Low Voltage, for those who wants the absolute best low voltage PSU.

 

There are of course several other combinations possible.

 

The  "FAT" are squarish with transistors mounting along the long side. Both sides > 2U.

The "Skinny" is rectangular with transistor mounting along the short side which is < 2U (thus can be mounted upright in a 2U chassie),

version 6 of the lv boards posted, same as previous version except added the optional pot and resistors

version 7 of the boards posted, 4.1 inches long, because one person wanted bigger power supply caps

dual version 6 as previous version with the optional pots and resistors

 

version 6 singles are 3.725 x 2.4

version 7 singles are 4.1 x 2.4

dual version is 3.67 x 4.32

 

with respect to the 2 singles in series, you really need 1 of each of the 2 boards, not 2 of 1 of them for lowest noise.

(not that its really measurable on any dvm < about $5k)
