We get a lot of really neat equipment in the shop - but this is definitely in the top 1% of what we've ever seen.

This is the later version of this renowned tuner, and is branded "Day Sequerra".

This is a more modern take of the Sequera FM Reference.

In perfect working condition, finished in a super rare dark gray aluminum, and featuring balanced outputs in addition to the usual single ended.

The CRT Scope is super bright and very responsive.

These PDF links may not match up to this exact model, but are close enough for historical purposes.

And check out our video below from a different Seuqerra tuner that recently sold.

Our Testing Process for Tuners at SkyFi:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and tubes are inspected for signs of stress overheating or cracking.

Then the tuner is thoroughly tested in our lab utilizing our professional Sencore SG80 FM Generator, which allows us to generate a reference FM signal of any frequency and amplitude, and then measure the resulting tuner output on our Sencore PR81 or oscilloscope.  This unit passed with flying colors and produced a natural and warm sounding output.
