SRS Stanford Research Systems PERF10 10MHz Rubidium atomic audio clock

For sale is rare SRS PERF10 10MHz Rubidium atomic audio clock.
I have used it with my Esoteric K-03 SACD player and N-05 network stream player and it worked flawlessly and improved the sound significantly. I am selling it due to upgrade.
It comes with original package and manual.

Only ship to CON US and  buyer pays actual shipping. I will  cover Paypal fee at my asking price.

From SRS official website:
The PERF10 is built around Stanford Research Systems' own PRS10 rubidium oscillator. By designing and building the oscillators ourselves, we're able to craft an instrument perfectly matched to the demanding requirements of audio master clocks.

Starting with an oven stabilized, 3rd overtone, varactor tuned, SC-cut crystal oscillator, the PERF10 offers both the accuracy and stability associated with rubidium clocks and unmatched jitter performance - 30 dB better phase noise at 10 Hz off carrier than a competing "Swiss-made" rubidium clock.

And because we don't have to buy our oscillators from an outside source, we can offer you perfection - at an affordable price.

PERF10 has eight 10 MHz, 75 Ω outputs compatible with all master clocks that accept a 10 MHz reference input.

Highlights: -Atomic stability and accuracy -Eight 10MHz, 75 Ω outputs -10 year aging less than 5 ppb -Ultra-low phase noise

Phase noise (SSB) <-130 dBc/Hz (10 Hz) <-140 dBc/Hz (100 Hz) <-150 dBc/Hz (1 kHz) <-155 dBc/Hz (10 kHz)

Outputs
-Number of outputs 8 BNC (rear panel)
-Output impedance 75 Ω
-Output amplitude 1 Vpp (terminated in 75 Ω)

Dimensions 19" W × 3.5" H × 10.125" L
Weight 8 lbs.
