Arrow DAC AD1955 board

Assembled AD1955 DAC board. Has DIR9001 receiver and OP275 opamps.
National Semiconductor LM317T, LM337T. ON-Semi MC7805CT voltage regulator.
PCB size: 112mm x142mm

Input voltage AC15-0-AC15V (12-16V is ok) and 0-AC9V (7-9V is ok)
You need only to add transformer(s)

Coaxial, optical fiber, USB input.
I used this board only a very short time for evaluation. Working AOK. Opamps are in sockets so can be easily upgraded.
Price $ 80. Will ship WW at cost.
