Up for sale is an original, highly collectible vintage Hammond Organ Company amplifier driver circuit board assembly. Pulled from a classic early 1970s console organ network, this board is the central processing brain for splitting and driving the audio to the Main speaker array, the internal Leslie rotary speaker system, and the spring reverb tank.
This board features original factory-stamped markings (023-041224, 124-000162, and ISSUE C). It is heavily loaded with iconic, high-grade vintage components—including rare striped "tropical fish" tone capacitors, premium resistors, radial capacitors, a central finned aluminum transistor heatsink, and clearly labeled terminal pins along both vertical sides for seamless wire reconnection.
Perfect as a direct drop-in replacement to fix a down vintage Hammond R-series organ, or as a component donor board for custom DIY guitar effects pedals, boutique tube amplifiers, and studio gear.
Condition: • Cosmetic: Excellent vintage cosmetic condition. The board itself is clean, rigid, and free of cracks. All silk-screened terminal text markings are sharp and highly legible. Components are physically intact with no signs of overheating or swelling.
Carefully removed from a fully functional Hammond organ.
Has not been tested after removing, has been well cared for while in the stores storage.
