organdonor amplification Rainmaker 15 watt all tube guitar amp EL84/12AX7

The Rainmaker 15 SN .007 is built from a 1960's Hammond organ power amp chassis completely converted into an all tube guitar amp.  This is a custom hand built circuit based on the classic spitfire amp with master volume, tone and volume.  The amp's foundation is a Hammond power transformer, output transformer and choke. New power supply capacitors, carbon composition resistors and  tone circuit components built point to point with terminal strips.

Amp produces both detailed chime cleans and high gain distortion with articulate note clarity typical of a class A cathode bias push-pull output section.  Touch responsive and master volume allows high gain drive at a lower volume. The eq is interactive and produce a wide variety of tones for both clean and over driven sounds. The amp sounds excellent as a platform for effect pedals. Input and power supply grounded separately for low noise.   5Y3 Rectifier, 2 x 6BQ5/EL84/7189 output tubes.  Many types of preamp tubes 12AU7,12AY7, (12BH7, 12AT7 phase inverter) can be used for desired level of gain, output volume and tone.  New filter capacitors, carbon composition and metal film resistors, switchcraft output jack, marshall style high and low impedance input jacks, Alpha pots and marshall style control knobs. Black face plate for a clean look when mounted in a cab.

Chassis dimensions: 12 L x 7 D x 6 H   Front panel opening: 10 L x 2 1/4 H

A note to buyers: The Hammond chassis I build these amps from are becoming scarce and cost is going up so I have to raise selling price to offset the difference.  Thanks for your consideration.
