{"product_id":"ampeg-1966-j-12-d-combo-amp","title":"Ampeg 1966 J-12-D Combo Amp, Excellent","description":"\u003cp\u003e\u003cstrong\u003eNo sales tax for US customers outside California.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis Ampeg J-12-D in excellent condition throughout: the original blue checker vinyl covering is intact, the blue sparkle weave grille is undamaged, and the birch plywood cabinet and baffle are both original and in excellent shape. The chassis is original, unmolested, and also in excellent condition.  The amps is a 20-watt, all-tube combo built around two 7868 pentodes and two 6BK11 triode-pentode preamp tubes — a configuration that produces clean headroom with a firm, detailed midrange character typical of Ampeg's mid-sixties guitar lineup - plus onboard tremolo. \u003c\/p\u003e\n\u003cp\u003eDating to 1966 per the serial number and component date codes, this is a fully correct mid-decade example. These amps are increasingly sought by players who want a vintage American tube combo that isn't a Fender, and by collectors focused on Ampeg's guitar amp output before the brand pivoted almost entirely to bass.\u003c\/p\u003e\n\u003cp\u003eThe original speaker is included but needs a recone and is not currently installed. A non-original Warehouse American Vintage G12C (12\") is installed and in excellent condition. The leather handle has been replaced. The filter cap can and other electrolytic capacitors have been replaced as a maintenance upgrade. Knobs and potentiometers are original. Power and output transformers are both original Electrical Windings units (PT-110 and OT-151A respectively). The power cable has been updated to a grounded three-prong. No case or cover is included.\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\"\u003eWhere Is Date Noted?: serial#, codes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWeight: 30lbs 5oz\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eDimensions: W19\" x D10-1\/4\" x H14-1\/8\"\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWatts: 20 watts\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCase\/Cover?: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Material: vinyl\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Color: Blue Checker\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Material: birch plywood\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Condition: excellent\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: blue sparkle weave\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eGrille Condition: excellent\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eGrille Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eBaffle Material: birch plywood\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eBaffle Condition: excellent\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?: no\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Brand: Non Orig Warehouse American Vintage G12C, Original speaker included, needs recone.\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Size: 12\"\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Cone Code: 21096\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Cone Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Condition: excellent\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Manufacturer: Electrical Windings\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Manufacturer: Electrical Windings\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: tremolo\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePedal Included?: no\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Tubes: 2 x 7868\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePreamp Tubes: 2 x 6BK11\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePotentiometers Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eFilter Caps: upgraded\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eInternal Repairs: The filter cap can was changed, along with other electrolytic caps in the circuit\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\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSmells?: none\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eSpeaker 1 Original?: no\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Model Code: PT-110\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Model Code: OT-151A\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;
