HARMAN KARDON CITATION 17S PREAMPLIFIER
REBUILD AND RESTORATION SERVICE
THIS LISTING IS FOR REBUILD/RESTORATION SERVICE ONLY.
THIS MEANS YOU SEND YOUR PREAMP TO ME FOR SERVICE.     AFTER THE REBUILD, YOUR PREAMP IS RETURNED TO YOU.   THE PICTURED PREAMP IS NOT FOR SALE.  PHOTOS ARE FOR ILLUSTRATIVE PURPOSES ONLY AND DO NOT REPRESENT THE EXACT REBUILD AS DESCRIBED IN THIS LISTING.
THE CITATION 17S PERFORMANCE AND BUILD QUALITY HAS BEEN WELL ESTABLISHED OVER THE YEARS.
AT THIS POINT IN TIME THE ORIGINAL UNITS SIMPLY DON'T SOUND "AS NEW".      TIME HAS AUDIBLY DETERIORATED PERFORMANCE.     IN PARTICULAR, DEFECTIVE CAPACITORS ARE UNDERMINING RELIABILITY AND IS THE LEADING CAUSE OF CIRCUIT FAILURE AND DEGRADED SONICS.
THE ELECTROLYTIC CAPACITORS ARE LONG PAST THEIR RECOMMENDED LIFE SPAN.   THEY CANNOT BE "REFORMED" NOR SALVAGED, AND MUST BE REPLACED.   REGARDLESS IF AN ORIGINAL PREAMP "BENCH TESTS" TO SPEC, IT'S ONLY GOOD FOR THAT INSTANT IN TIME.    WITH THE ORIGINAL COMPONENTS STILL INSTALLED, IT COULD FAIL AT NEXT TURN ON.     THERE IS NO LONG TERM RELIABILITY.
ANY DIRECT COMPARISON TO A PROPERLY RECAPPED, UPGRADED, AND SERVICED CITATION 17S...... THE DIFFERENCES AND IMPROVEMENTS ARE IMMEDIATELY OBVIOUS.
THE OVERALL TONAL CHARACTER OF THE REBUILT PREAMP REMAINS THE SAME AS THE ORIGINAL.     HOWEVER, THE NOISE FLOOR IS DRAMATICALLY LOWERED.     THE BACKGROUND IS DEAD SILENT.    LOW LEVEL DETAILS AND NUANCES OF THE MUSIC THAT WERE LOST IN THE "GRUNGE" CAN NOW BE HEARD.      HIGH AND LOW FREQUENCY EXTREMES ARE EXTENDED.    OVERALL CLARITY AND FOCUS IS NOTICEABLY IMPROVED, WITH A LARGER, LAYERED SOUND STAGE.
I'VE REBUILT A LARGE NUMBER OF CITATION 11, 17, AND 17'S OVER THE PAST 15 YEARS.    SOLD AS BOTH AS REBUILDING SERVICES AND COMPLETED UNITS ON EBAY.   CHECK MY SELLER'S FEEDBACK.     THE TECHNIQUES AND COMPONENTS PREVIOUSLY USED IN THESE REBUILDS PROVIDE PROVEN RESULTS.
SPECIFIC SERVICE INCLUDES:
THE POWER SUPPLY IS TOTALLY REBUILT WITH 2 PREMIUM NICHICON "KZ MUSE" ELECTROLYTIC CAPACITORS.   MAIN POWER CAPACITANCE IS MORE THAN DOUBLED.   2 NEW VOLTAGE REGULATORS.  11 LOW NOISE 1% METAL FILM RESISTORS REPLACE THE ORIGINAL CARBON.   4 INDIVIDUAL ULTRA-FAST "SOFT RECOVERY" DIODES REPLACE THE STANDARD SINGLE BRIDGE RECTIFIER.       8 KZ MUSE CAPACITORS INSTALLED IN THE  SECONDARY POWER CIRCUITS.
RELAY CIRCUIT RECEIVES 2 HI-TEMP/LOW ESR CAPACITORS
THE OUTPUT, PHONO, AND FILTER BOARDS HAVE ALL THE ELECTROLYTIC CAPACITORS REPLACED.   EVERY CERAMIC "DISC" CAPACITOR (12 TOTAL) IS REPLACED.      NON-POLAR CAPACITORS REPLACED WITH SILVER MICA, METALIZED POLYPROPYLENE, OR PRECISION MULTI-LAYERED CERAMIC AS REQUIRED.    22 ELECTROLYTIC CAPACITORS ARE REPLACED WITH NICHICON KZ, KA, FG, AND NICHICON ULTRA LOW IMPEDANCE CAPACITORS DEPENDING UPON THE CIRCUIT APPLICATION.
THE INCANDESCENT POWER INDICATOR LIGHT IS REPLACED WITH AN LED.     THE LED SUPPLY VOLTAGE WILL BE SLIGHTLY LOWER THAN THE RECOMMENDED VOLTAGE.     THIS WILL EXTEND LED LIFE EVEN LONGER THAN USUAL.
ALL SWITCHES, AND CONTROLS ARE PROPERLY CLEANED AND SURFACE TREATED WITH "CAIG" PRODUCTS.    THE VOLUME ATTENUATOR IS SEALED.    THE ATTENUATOR IS REMOVED FROM CHASSIS, CASE OPENED TO ACCESS THE "WIPERS", AND PROPERLY CLEANED.   THERE ARE NO SHORT CUTS TO CLEAN THE ATTENUATOR THOROUGHLY.   THE ORIGINAL SILICON LUBRICANT IS OFTEN "GUMMED UP" FROM AGE AND NEEDS TO BE FLUSHED OUT.
PREAMP WILL HAVE A MINIMUM 12 HOUR "BURN IN" AND ALL FUNCTIONS TESTED.
REBUILD SERVICES FOR THE 17 PREAMP ARE ALSO AVAILABLE.     DUE TO THE ADDITIONAL (2) TONE CONTROL BOARDS, WITH A LARGE NUMBER OF PRECISION CAPACITORS, COST WOULD BE HIGHER.    A COMPLETE SEPARATE LISTING MUST BE POSTED TO COVER THAT PURCHASE.
ADDITIONAL UPGRADES FOR BOTH THE 17 AND 17S ARE AVAILABLE AT EXTRA COST.     SELECTED UPGRADES WOULD BE POSTED AS A SEPARATE "BUY-IT-NOW" LISTING PER EBAY POLICY.     CONTACT ME FOR DETAILS.
HERE IS THE FINE PRINT.    READ CLOSELY...........
NON-WORKING PREAMPS ARE ACCEPTABLE FOR REBUILD, BUT ONLY IF I AM CONTACTED FIRST THROUGH EBAY MESSAGE SYSTEM.  ALL BOARDS AND MAJOR COMPONENTS MUST BE PRESENT.    I MUST AGREE TO ACCEPT THE NON-WORKING PREAMP BEFORE PURCHASE.
OFTEN, THE REBUILD SERVICE WILL RESTORE A NON-FUNCTIONING PREAMP BACK TO OPERATING CONDITION.    HOWEVER,  ANY PARTS REPLACEMENT/LABOR BEYOND WHAT IS SPECIFICALLY STATED IN THE REBUILD SERVICE...... WILL INCUR ADDITIONAL COST.    THESE ADDITIONAL CHARGES WOULD BE POSTED AS A "BUY-IT-NOW" AFTER REPAIRS ARE COMPLETE, PER EBAY POLICY.
DUE TO A LIMITED AVAILABLITY  OF USED PARTS AND/OR ACCEPTABLE NEW REPLACEMENTS, REPAIRS OF BROKEN SLIDERS, SWITCHES, AND CONTROLS CANNOT BE GUARANTEED.
I WILL NOT BE HELD LIABLE FOR "NO REPAIR" IF THE BUYER FAILS TO TRUTHFULLY DISCLOSE CONDITION OF THE NON-FUNCTIONING PREAMP.   HE WILL BE CHARGED FOR MY TIME AND PREAMP RETURNED AT HIS COST.
U.S. SALES ONLY.
