Marble Vintage Amplifiers

The MARBLE Vintage series consists of a collection of single-channel tube amplifiers. These amps feature full tube circuitry, tube-driven reverb and tube-rectified power supply (not for the Guitarman). All MARBLE vintage series amps are point to point wired with only the best quality parts available to insure superb performance with a vintage character.

Output transformers are handwound in the transformer department. To obtain the right amount of saturation effects like natural roll-off at full power, a paper bobbin construction with the correct amount of interleaving to match is used. High quality heat-treated lamination and vacuum impregnation finishes the transformers. U.L. approved judd wire (300-600V) is used on all transformers and they are tested for 2KV insulation at full power before use.

The chassis are made of high quality steel and finished with triple-plated chrome. All Vintage series cabinets are made from scandinavian solid pine. After assembly the cabinets are covered with impregnated tweed cloth and lacquered and aged on MARBLE's distinct patented procedure. There is a wide range of optional finishes for Tolex fans.

The circuitry is constructed traditionally on noninductive eyelet boards with silver coated eyelets. Special U.L. Judd wire is used in the power supply. Vintage push-back wires are used for the remaining connections inside. Only heavy duty- and quality parts are used. Brands of the parts used are Bradley, Stackpole, Sprague, Saha, Xicon, IC, Switchcraft, Sovtek ceramics, Accutronic and Carling.

MARBLE offer a wide range of speakers for their vintage series amps. Most standard models come with Jensen Reissue speakers. These are good quality and cost-effective speakers with the right tone and attitude. For other speaker options like Celestion Eminence or WeberVST ask your MARBLE-dealer.

MARBLE Harp amps are built with exactly the same philosophy. The harp amps use output transformers that closly resemble the original Bassman 59 concept in respect of bobbin type, interleaving, lamination and aging to obtain the perfect mix of smooth tone and compression.
