Lightbulb FS: 2pcs DEXA/NewclassD 7915 voltage regs, ultra low noise, different -VDC possible

Hi, for sale are two pieces NewclassD / DEXA ultra-low-noise voltage regulators. They are both NEW and have never been used.

Features are ultra-wide bandwidth, very low noise, and miles above the performance of the usual monolithic regs like standard 7915, 337, etc. NOTE: can easily be converted to -3.3V, -5V, -9V, -12V by changing a *single* resistor value

PRICE: USD 20,- each, while from DEXA they cost new USD 37.27 EX VAT (!) They have never been used, see pic

Please see NewClassD UWB Regulator for more details.

I intended to build a dual-mono linestage with them, but never got to build one since my source equipment changed. Never been used / soldered. Of course they have been tested at danish company NewclassD for specs etc.

Type: 7915 neg.
Output Voltage: -15V DC
Input Voltage: max. 25V DC
Dropout Voltage: 2.00V (Equivalent to 79XX series)
Maximum Current DX79xx: 400mA
Ripple Rejection: >100dB
Line Rejection: unmeasurable
Load Regulation: < 5mV 0-max load
