Marantz ST6000 FM Tuner With Remote and Box – Modified. Notes. In the lab we found this unit to display good channel separation and dial tracking. Display is a little dim but still very visible. Clean cosmetic condition with little signs of use. Lastly there’s a mysterious potentiometer on the back panel that did not affect audio signal or signal strength in our bench tests. Not sure what it does exactly, and a sticker on the back reads “Audio quality enhanced” The SkyFi Testing Process for Tuners: 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. 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. 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. Stereo Separation – A properly working stereo tuner will have minimal crosstalk between the left and right channel. 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. 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. No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. If we don’t have the original manufacture’s packaging, we use heavy duty double-ply corrugated boxes with custom made to your item SealedAir Instapak expanding foam custom inserts. In many cases this has proven to be better than the original packaging! We also use high quality fiber reinforced tape to seal our packages. We have too many items for sale and it is nearly impossible to keep track of offers outside of the official system. Please understand we have no control over this.
