It comes with an added bonus: a Studio Slips cover.  I love the 60s looks, and the low power tone is killer at a volume level that is very useable.\u003c\/p\u003e\n\u003cp\u003eWe have a couple different, matching cabinets from this series that we will list soon - a 1x12 and a 2x12.\u003c\/p\u003e\n\u003cp\u003eThe ST20H MKII is Marshall's modern take on the JTM45 circuit — their earliest production amp design — built into a compact studio-friendly head format. The switchable 20\/5-watt power section gives players access to genuine power tube saturation at manageable volumes. The cabinet is finger jointed plywood wrapped in original black vinyl with a wheat grille. Power is supplied by a pair of 5881 power tubes, a close relative of the 6L6, which in JTM-style circuits produces warm tones with fuller low-end response than EL34-based Marshall designs. Three ECC83 preamp tubes handle gain staging. The amp is all original.  The tubes were tested in our shop to make sure the amp is good to go on arrival without additional expense.\u003c\/p\u003e\n\u003cp\u003eThere are no repairs, changes, or issues with this amp. The cabinet, chassis, covering, grille, and cover are all in excellent condition. The power cable 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: 2023\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWhere Is Date Noted?: Serial #\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWeight: 20.4 lbs\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eDimensions: 19.7\" (Width) x 9.4\" (Height) x 9.1\" (Depth)\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eWatts: 20 \/ 5 watts switchable\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCase\/Cover?: Studio Slips Cover\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCase\/Cover Condition: excellent\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Material: vinyl\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Color: black\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCovering Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eCabinet Material: finger jointed 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: wheat\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\"\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: rubber\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eHandle Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Manufacturer: Marshall\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Manufacturer Code: TXMA\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Date Code: MAV 23 04\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Transformer Original?: yes\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Manufacturer: Marshall\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Manufacturer Code: TXOP\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003eOutput Transformer Date Code: MAV 23 05\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\"\u003ePower Tubes: 2 x 5881\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePower Tube Brand: Marshall\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePreamp Tubes: 3 x ECC83\u003c\/li\u003e\n\u003cli class=\"product-spec\"\u003ePreamp Tube Brand: Marshall\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\"\u003ePower Cable: included\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\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 href=\"https:\/\/www.maharsvintageguitars.com\/collections\/amps\" title=\"Vintage and used guitar amplifiers at Mahar's Vintage Guitars\"\u003eVintage \u0026amp;

Depending on the amp, this may include removing tubes, pulling the chassis from the cabinet if heavy transformers present a drop risk, or removing heavy speakers that could crack baffles in transit. Reassembly is required on delivery — we label everything clearly. These measures add to shipping costs but reflect hard-won experience. \u003cb\u003eVintage amplifiers (20 years or older) are sold as-is\u003c\/b\u003e — all amps are tested in our shop upon intake and again before shipping.
