The Pro-Amp is the unsung hero of that golden-era lineup — the tweed era's best-kept secret. The Fender Professional Amplifier predates all of them in the lineup hierarchy. It was Leo Fender's flagship professional instrument from the late 1940s onward — the amplifier that working musicians chose when they needed the most Fender had to offer. The 5A5 is the earliest circuit designation in the TV-front Pro series, used from the late 1940s through roughly 1951, before the 5B5 revision took over. A 1950 example with the 5A5 circuit is among the oldest surviving TV-front Pros in any condition — and this one is in excellent shape throughout.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cspan class=\"inline-flex\" data-state=\"closed\"\u003e\u003ca href=\"https:\/\/usa.yamaha.com\/products\/contents\/guitars_basses\/history\/chronology\/index.html\" class=\"group\/tag relative h-[18px] rounded-full inline-flex items-center overflow-hidden -translate-y-px cursor-pointer\" target=\"_blank\"\u003e\u003cspan class=\"relative transition-colors h-full max-w-[180px] overflow-hidden px-1.5 inline-flex items-center font-small rounded-full border-0.5 border-border-300 bg-bg-200 group-hover\/tag:bg-accent-900 group-hover\/tag:border-accent-100\/60\"\u003e\u003cspan class=\"text-nowrap text-text-300 break-all truncate font-normal group-hover\/tag:text-text-200\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003eThe Fender Pro Amp was a groundbreaking guitar amplifier in its day, delivering impressive tone and power that made it a stage-worthy professional-grade option for the performing musician. With its unique TV-front tweed-wrapped pine cabinet and single 15\" speaker delivering upwards of 18-20 watts output, it secured itself as one of Fender's most crowning achievements in the budding industry of electric guitar. The TV-front cabinet design — named for the squared-off front panel that resembles a 1950s television set — is the visual signature of the earliest Fender production era, before the wide-panel and narrow-panel tweed cabinets of the mid-to-late-1950s replaced it. Original pine cabinet, original brown grille cloth, original tweed covering, all in excellent condition. \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cspan class=\"inline-flex\" data-state=\"closed\"\u003e\u003ca href=\"https:\/\/reverb.com\/item\/17820268-yamaha-bb-g5-5-string-electric-bass-high-definition-tiger-amber-burst-top\" class=\"group\/tag relative h-[18px] rounded-full inline-flex items-center overflow-hidden -translate-y-px cursor-pointer\" target=\"_blank\"\u003e\u003cspan class=\"relative transition-colors h-full max-w-[180px] overflow-hidden px-1.5 inline-flex items-center font-small rounded-full border-0.5 border-border-300 bg-bg-200 group-hover\/tag:bg-accent-900 group-hover\/tag:border-accent-100\/60\"\u003e\u003cspan class=\"text-nowrap text-text-300 break-all truncate font-normal group-hover\/tag:text-text-200\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003eThe 5A5 circuit uses the 6SC7 octal double-triode preamp tube — the same preamp architecture found in the PA amplifiers and phonograph amps of the period, carried into the guitar context by Leo Fender in these earliest designs. The cathode-biased pair of 6L6G power tubes along with the 6SC7 preamp provide lush tube power that saturates into overdrive with a woody and harmonically rich response. The Pro-Amp excels at delivering pristine, articulate clean tones perfect for country and jazz, yet when driven hard produces a warm, harmonically complex breakup ideal for blues and rock.  The single 15-inch speaker and compact power section create a tighter, more focused sound signature than the Bassman. Past about 6 on the volume control it doesn't get any louder, just gives more sustain and body — the 15\" speaker simply barks the blues. Playing slide through one of these is magical. \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cspan class=\"inline-flex\" data-state=\"closed\"\u003e\u003ca href=\"https:\/\/reverb.com\/item\/17820268-yamaha-bb-g5-5-string-electric-bass-high-definition-tiger-amber-burst-top\" class=\"group\/tag relative h-[18px] rounded-full inline-flex items-center overflow-hidden -translate-y-px cursor-pointer\" target=\"_blank\"\u003e\u003cspan class=\"relative transition-colors h-full max-w-[180px] overflow-hidden px-1.5 inline-flex items-center font-small rounded-full border-0.5 border-border-300 bg-bg-200 group-hover\/tag:bg-accent-900 group-hover\/tag:border-accent-100\/60\"\u003e\u003cspan class=\"text-nowrap text-text-300 break-all truncate font-normal group-hover\/tag:text-text-200\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003eThe 15\" Jensen Alnico 5 speaker is the original unit, speaker manufacturer code confirming Jensen production from week 7 of 1950. The speaker has been professionally reconed, well before it was stashed in a closet back in 1990. Both original Triad power and output transformers are intact. The filter caps are brand new, the correct and responsible service approach for a 75-year-old amplifier. The INST channel volume pot has been changed with a late 50s, correct spec pot— the remaining two pots are original. The leather handle is a beautiful reproduction that is the best replacement in the business. Power cord has been upgraded to grounded three-prong. The chassis carries the stamps and signatures of a repair shop right here in Chico, CA— a shop that dated back to the 1950s. RCA 6L6 power tubes, RCA 5U4 rectifier, three RCA 6SC7 preamp tubes.
