VINTAGE MAGNAVOX 6V6 AMPLIFIER (AMP 169 BB)- REBUILT W/ UPGRADED COMPONENTS







2 VINTAGE MAGNAVOX 6V6 (PUSH-PULL) MONO AMPLIFIERS

MODEL "AMP 169 BB"

RECAPPED AND REBUILT WITH UPGRADED COMPONENTS

 

 

THE VINTAGE MAGNAVOX "CONSOLE" AMPLIFIERS HAVE GARNERED SOME ATTENTION IN THE PAST YEAR, OR SO.       INDIVIDUALS ARE FINDING OUT THEY SOUND PRETTY GOOD.      ITS TRUE TO A CERTAIN POINT.       THE MIDRANGE SOUNDS AWESOME, HOWEVER AT THE FREQUENCY EXTREMES......NOT SO MUCH.      EXTENDED LISTENING PRESENTS BASS THAT IS NOT DEFINED AND HIGH FREQUENCIES THAT ROLL OFF.       THESE AMPS SUFFER FROM "AGE" AND USE RELATED PROBLEMS THE SAME AS ALL VINTAGE UNITS.

IF YOU BELIEVE THE ORIGINAL VERSIONS SOUND THE BEST, THESE AMPS ARE NOT FOR YOU.     A REBUILD WITH HIGHER QUALITY RESISTORS AND A RECAP WITH NEW CAPACITORS DOES IMPROVE THE SOUND.     THE DIFFERENCE IS QUITE NOTICEABLE AND IMMEDIATE.      THE SOUND IS "CLEANER" WITH NO BACKGROUND NOISE.     SAME GLORIOUS MIDRANGE, THE BASS IS TIGHTER AND MORE DETAILED.     "SPARKLE" IN THE HIGH END HAS RETURNED.   THE OVERALL SONIC PRESENTATION IS MORE ACCURATE.


THE BOTTOM BASE.       MOST CONSOLE AMPS HAVE NO BOTTOM PLATE PROVIDED.      WHILE THEY CAN FUNCTION FINE WITHOUT ONE, FOR SAFETY'S SAKE, ITS ALWAYS A GOOD IDEA.      A BETTER IDEA, IS TO PROVIDE A SHIELDED BASE THAT PROVIDES MORE RFI/EMI PROTECTION, AND REDUCES "HUM" PROBLEMS.       WITHOUT A SHIELDED BOTTOM, THE AMPS CAN HAVE ISSUES WITH INDUCED HUM FROM NEARBY UNITS/WIRING.      THE SHIELDED BASE MAKES A LARGE IMPROVEMENT IN ELIMINATING AND/OR REDUCTION IN THESE "HUM" RELATED PROBLEMS.

THESE BASES ARE FABRICATED FROM 7/16" BALTIC PLYWOOD, WITH A .010" THICK ALUMINUM SHEET BONDED TO THE INNER SURFACE.

ALL NON-ESSENTIAL AND NON-FUNCTIONING WIRING WAS REMOVED.

EXCEPT FOR A SINGLE 2 WATT RESISTOR IN THE POWER SUPPLY, ALL OF THE ORIGINAL CARBON COMPOSITION RESISTORS WERE REPLACED WITH LOW NOISE 5% METAL OXIDE, OR 1% METAL FILM RESISTORS.    (1) 4.7 MEG VALUE WAS UNAVAILABLE IN METAL FILM, AND REPLACED WITH A CARBON FILM RESISTOR.     ANOTHER 2 WATT CARBON RESISTOR WAS REPLACED WITH A 5 WATT WIRE WOUND VERSION.

2 SEPARATE ELECTROLYTIC CAPACITORS (1 IN A BIAS SUPPLY VOLTAGE AND 1 IN FEEDBACK CIRCUIT) WERE REPLACED WITH THE SAME VALUE CAPS.   ORIGINAL CAP VALUES WERE WAY OFF, ESPECIALLY THE FEEDBACK CAP.       THAT CAPACITOR IN THE FEEDBACK CIRCUIT WAS REPLACED WITH A  NICHICON "KZ MUSE" AUDIO GRADE CAPACITOR.

THE ORIGINAL 4 SECTION POWER SUPPLY CAPACITOR MEASURED IN SPEC. AND (SURPRISINGLY) HAD NO AUDIBLE BACKGROUND NOISE.       INSTEAD OF REPLACEMENT, I PARALLELED NEW CAPACITORS TO 3 OF THE SECTIONED CAPACITOR BANKS.      MAIN POWER SUPPLY CAPACITANCE WAS DOUBLED.      THE 2 OTHER POWER SUPPLY CAPACITANCES WERE ALSO INCREASED APPROX. 25%.       THE 4TH CAPACITOR BANK WAS FOR THE TUBE BIAS.      THAT CONNECTION (AND CAPACITOR BANK) WAS REMOVED FROM THE CIRCUIT.      IT WAS REPLACED WITH A SEPARATE ULTRA LOW ESR NICHICON ELECTROLYTIC CAP, THAT DOUBLED THE BIAS CAPACITANCE.

THE ORIGINAL 0.01mf CERAMIC DISC CAPACITOR THAT WAS SITUATED DIRECTLY IN THE AUDIO PATH, WAS REPLACED WITH A "DAYTON" POLYPROPYLENE FILM/FOIL CAPACITOR.

AN ON/OFF SWITCH WAS INSTALLED.

GOLD PLATED RCA JACK REPLACES THE ORIGINAL.

GOLD PLATED SPEAKER TERMINALS REPLACE THE ORIGINAL "SCREW TERMINALS".

NEW 6 FOOT POWER CORDS.

OUTPUT TUBES ARE ORIGINAL AND MEASURE BETWEEN 90 AND 95 ON MY CALIBRATED JACKSON 648S.      MEASUREMENTS ARE WRITTEN ON TOP OF EACH TUBE.      5Y3GT RECTIFIER TUBES ARE ORIGINAL AND ALSO MEASURE STRONG.      THE GE 6AN8 TUBES ALSO MEASURE 95 TO 100 ON ALL SECTIONS.     

THE AUXILLARY AC PLUG ON EACH AMP IS SWITCHED.     THE AMP HAS TO BE "ON" FOR PLUG TO WORK.

ONE .047mf "BUMBLE BEE" CAPACITOR WAS DEFECTIVE IN ONE AMP.   IT WAS REPLACED WITH A SPRAGUE BLACK BEAUTY.   

YOU WILL ALSO NOTE (SEE PHOTO) THAT ONE TRANSFORMER BELL IS SLIGHTLY TALLER THAN THE OTHER.      SAME TRANSFORMERS, JUST DIFFERENT BELL HOUSING.     I'VE SEEN THE SAME WITH OTHER PAIRS OF 169 BB AMPS.     WITH THE EXCEPTION OF THE SINGLE .047 CAPACITOR AND HEIGHT OF THE BELL HOUSING, BOTH AMPS ARE IDENTICAL IN CONSTRUCTION/APPEARANCE.


AMPS ARE SOLD AS-IS.      NO WARRANTY IS IMPLIED.     


COSMETICALLY, THE AMPS ARE CLEAN.     TRANSFORMER BELLS HAVE SMALL NICKS.     NO RUST.    INSPECT PHOTOS CLOSELY.
