Day Sequerra FM Studio Tuner - Factory Serviced - Balanced XLR Outputs

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
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.

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

Check out our full walkthrough video from a different Day Sequerra tuner that recently sold for an understanding of features and functions.


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

The CRT Scope is super bright and very responsive.

Technical Notes:
This unit was previously serviced at some point in its life by Analogique in NYC. Our bench testing showed some minor issues so we sent it out to Day Sequerra for an evaluation. The unit was inspected, repaired as needed, aligned, and given a clean bill of health.

This tuner will arrive safely in a factory box.

Testing Process:

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. Vintage analog tuners also have moving parts related to the tuning gang and dial string. These parts are inspected for smooth operation.

If the unit passes visual inspection it is bench tested for a handful of key performance parameters using a Sencore SG80 AM/FM Stereo Analyzer. The SG80 allows us to “simulate” an ideal radio station using precision test signals instead of music. This device, in conjunction with an oscilloscope allows us to properly evaluate the following parameters:

1.  AM Reception (Where Applicable)

2.  FM Mono Reception & Tuning Meter Function

3.  FM MPX Reception (Stereo)

4.  Dial Tracking - How accurately the tuner dial or display indicates the actual frequency of the broadcast being received.

5.  Stereo Separation - A properly working stereo tuner will have minimal crosstalk between the left and right channel.

6.  Sensitivity & Signal Strength Meter Function - By lowering the output of the SG80 we can simulate weak stations and determine how well the tuner will be able to pull in weak distant stations. This adjustment also helps us verify signal strength meter function.

If the tuner has acceptable performance related to the parameters above we connect the unit for listening tests with a simple dipole antenna. We listen for audio reproduction quality of local stations and evaluate how many stations the tuner can receive while we sweep through the dial. We are looking to verify that the tuner can decode stereo on strong local broadcasts and pick up a wide variety of local stations at the bottom, middle, and top of the frequency band. At this point we also test convenience features such as muting, filters, built in oscilloscope function, etc.

We finish up with an extended listening test on our long term test rig. We tune in a strong local station and monitor for drift over a 2-3 hour period.
