Audio Research SP3-A1 Preamplifier One Owner, Gold Front Absolutely Mint Condition Selling my audio system of 40+ years. Here is the Preamplifier that I purchased around 1976 from Paul Heath Audio here in Rochester, NY. It was used with a Linn Sondek turntable and Quad ESL57 speakers to give wonderful female voices and guitar strings. It was stored in a closet for most of those years while the kids were growing up.Note that all the electrolytic capacitors are original. I recommend that you either leave power on all the time or slowly bring up the power with a Variac to preserve the capacitora dn the tube filaments. It still has the Telefunken tubes that I installed soon after purchase, and they still measure good on my TV7-D/U Tube Tester. Back then the Telefunkens were acclaimed to be the best, and I never had reason to change them. I spent most of the day today measuring and studying the tubes, as follows........ TUBE MANUFACTURE TYPE SYMBOL DATE CODE Gm V1 Telefunken 12AX7 Bottom Diamond B9014201 56/52 V2 Telefunken 12AX7 Bottom Diamond B9014201 52/52 V3 Telefunken 12AU7 B-PC-28 106/98 V4 Telefunken 12AX7 Bottom Diamond B9014201 45/54 V5 Telefunken 12AX7 Bottom Diamond B9014201 50/50 V6 Telefunken 12AU7 B-PC-28 100/100 V7 Telefunken 12AX7 B0BA-01 51/50 V8 Telefunken 12AX7 B-OB-01 46/52 They are all Telefunkens2 Cathode Followers are 12AU7 for lower output impedance. It was common back then.4 of the tubes have the Diamond on the bottom. and their date code 4th digit places their date of manufacture as 1964 and made in BerlinGm (Transcconductance) was measured on a calibrated TV7-D/U. Minimum for the 12AX7 is On these Preamps the rear panel only says SP3, and you have to look inside for the sticker below the transformer to see the A-1 label. Cosmetically the unit id truly mint. No scratches anywhere, showing how well it was cared for. For large items like this Fedex Ground is usually cheaper than USPS.

Jahrgang: Ab 1991 Seriennummer: 67337044 Zustand: Gebraucht, mit optisch feinsten Alters- und Gebrauchsspuren. Technisch ist das Gerät defekt. Ich bin der zweite Besitzer, der Vorbesitzer hat das Gerät vor etwa zehn Jahren revidieren lassen, bei dieser Revision wurden die Relais ersetzt, das Balance-Potentiometer überbrückt, und das Volume-Potentiometer gegen ein besseres von ALPS ausgetauscht. Der Besitzer besass eine Firma für Oberflächenveredelung, somit hat er die Frontplatte eloxiert, und dann graviert. Es handelt sich um die originale Front, nun einfach mit einer perfekten Gravur. Um den September 2023 begann ein Kanal merklich leiser zu spielen, und dann durch das Relais bei leisen Papieren teilweise aus zu setzen. Das Gerät ging dann in die Revision zum Techniker, wie meist sind diese massiv überlastet. Irgendwie hat er dann rein geguckt, jedoch wurde die Arbeit nicht fertiggestellt. Habe dann den Pre zu H-J. S. verfrachtet, welcher leider nicht mehr die Ressourcen hatte, somit habe ich die SP-9 zurück geholt. S. riet von einer Inbetriebnahme ohne vorhergehende Durchsicht ab. Da ich noch über weitere AR Preamps verfüge, lasse ich es somit nun bleiben. Der Verkauf erfolgt als zu 100% DEFEKT. Sonstiges: Sehr viele Informationen zu diesem Weltklasse - Vorverstärker finden sich auf dem WWW. Für gab es nie einen Grund, dieses Gerät aus zu tauschen, leider lässt es mein Arbeitspensum im Moment nicht zu, noch Stunden des Umherfahrens zu investieren, da höre ich lieber Musik :-) Das originale Manual, der Schaltplan und die Bauteile zur Anpassung des Phono-Eingang liegen bei. 220-Volt - Version. Biete / Kaufe nur, wenn du den Text lückenlos verstanden hast. Danke. ACHTUNG: Der Versand erfolgt aus der Schweiz. Bitte seien Sie sich bewusst, dass eventuelle Import - resp.
