oops, not precisely a 'giveaway'

i've already built mine and several others to phenomenal results. better than myref in my opinion, and better than most high end commercial offerings to my associates. with the salas shunt taking over the psu duty of the 1st gain stage, the sonic is truly unbelievable.

i still have plenty of pcbs left

http://www.diyaudio.com/forums/swap-meet/241696-miniref-pcbs-sale.html

price reduced to $5 +shippping. i just need to make back on the cost of fabrication.

for those who i still owe from the polystyrene group buy, please let me know your location and i will send you 2 pcbs for the price of shipping only.

best regards,

eric

Here's the thread:

http://www.diyaudio.com/forums/chip-amps/184165-miniref-schematic-pcb-layout.html

The schematics/layouts shown in the thread do not include the Salas shunt, which PreSapian added later.

I'll add that the MiniRef(s) have been tested with a wide variety of dual opamps, both monolithic and discrete, with minor compensation tweaks in some cases. I have a pair of FET990 discretes in mine, and PreSapian has tried my LF03d discrete in his MiniRef (which includes the Salas shunt). I expect that my LF05 folded-Kaneda Class-A discrete opamp will also work without any changes - will confirm that within a few days.
