The Altec 421A is a high-quality ceramic driver with a well-regarded reputation in bass applications, and its presence here elevates this above a stock B-15-N. Thirty watts through an efficient 15\" in a folded-cabinet enclosure delivers more usable volume and headroom than the wattage figure suggests. The amp is in excellent overall condition, with the chassis rated excellent and all the important original components intact throughout.\u003c\/p\u003e\n\u003cp\u003eThe Ampeg B-15-N — the \"Portaflex\" — defined the sound of recorded bass from the early 1960s through the 1970s. If you've heard a Motown record, a soul session, or a classic rock album from this era, you've heard this amplifier. The flip-top cabinet design, where the head stores inside the cabinet for transport, was an Ampeg innovation that solved the problem of gigging with a substantial amp while keeping it in a single manageable unit. By 1966, the B-15-N was a refined, mature design: 30 watts, a tube rectifier (5AR4), push-pull 6L6 output stage, and three 6SL7 preamp tubes — a topology that contributes directly to the amp's warm, harmonically full character. The original blue checker vinyl covering, silver sparkle grille, leather handle, and select hardwood cabinet and baffle are all present and original.\u003c\/p\u003e\n\u003cp\u003eThe cabinet is in very good condition with standard signs of love and use, and the baffle is very good as well — no repairs or changes to either. The grille is original. The chassis is excellent with no repairs or changes. All knobs, potentiometers, and the leather handle are original. Power and output transformers are original Ampeg units. Current tube complement: 5AR4 rectifier (Amperex), 2x 6L6 power tubes (JJ), and 3x 6SL7 preamp tubes (Magnavox, International C). Bypass caps have been updated, as has the power cable, which is now grounded. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"product-spec-list\"\u003e\n\u003cli class=\"product-spec\"\u003eDate: 1966\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWeight: 66 lbs\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eDimensions: (Closed \/ Head stored inside): H 21\" × W 21\" × D 14\", (Open \/ Head on top with caster dolly installed): H 33.5\" × W 21\" × D 14\"\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWatts: 30 watts\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCase\/Cover?: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Material: Blue checker vinyl\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Color: blue\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Material: select hardwood\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Condition: very good\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Repairs\/Changes: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eGrille Style: silver sparkle\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eGrille Condition: good\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eGrille Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eBaffle Material: select hardwood\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eBaffle Condition: very good\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eBaffle Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eBaffle Repairs\/Changes: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eChassis Material: metal\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eChassis Condition: excellent\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eChassis Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eChassis Repairs\/Changes: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eKnobs Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eHandle Material: leather\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eHandle Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Brand: Altec 421A\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Size: 15\"\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Cone Code: 21353-3\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Original?: No\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Cone Original?: Reconed\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Condition: excellent\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Manufacturer: Ampeg\u003cmeta charset=\"utf-8\"\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Manufacturer: Ampeg\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eReverb Onboard: no\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eTremolo Or Vibrato Onboard: no\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePedal Included?: no\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eRectifier Tube: 5AR4\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eRectifier Tube Brand: Amperex\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Tubes: 2 x 6L6\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Tube Brand: JJ\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePreamp Tubes: 3 x 6SL7\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePreamp Tube Brand: Magnavox, International C\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePotentiometers Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eFilter Caps: Original\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eInternal Repairs: unknown\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Cable: grounded\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eAccessories Included: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eDocumentation: none\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.maharsvintageguitars.com\/pages\/sell-vintage-guitars\"\u003eWe buy, sell, and take trades.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eBe sure to check out the other cool guitar related stuff on our site!\u003cbr\u003e\u003ca title=\"Vintage and used guitar amplifiers at Mahar's Vintage Guitars\" href=\"https:\/\/www.maharsvintageguitars.com\/collections\/amps\"\u003eVintage \u0026amp;
