Hi, I'm Frank Fendley, and I am your electronic repair specialist here at Uncle Sam's Jamms.   I received my bachelor's degree in electrical engineering at the University of Louisville Speed Scientific School in 1974, and completed additional post-graduate studies in digital electronics at the University of Alabama-Birmingham in 1987-1988. I've been repairing electronic musical equipment in the Louisville area for the past 38 years.  For technical tips on maintaining your equipment, visit my "Frank the Tech Guy" blog - click here.

We offer professional solid state and tube audio service, repair, restoration and modification for both current and vintage tube amplifiers, preamps, keyboards, speaker cabinets, mixers, power amplifiers, effects units, CD and karaoke players and other electronic musical instrument equipment.   We can repair all types of tube and solid state digital and analog audio gear from most all manufacturers.  Our onsite workshop is stocked with quality parts, professional test equipment, and the latest in service schematics and manufacturers' documentation.   Your equipment will be professionally diagnosed and serviced for best sonic performance and long-term reliability.    Uncle Sam's Jamms is the area's most complete service center, offering everything from classic tube amplifier service to replacement of the laser in your CD or karaoke player, to complete keyboard repair and professional speaker reconing.   Why go anywhere else?  Our complete focus is on the repair of your equipment - we aren't involved in other projects such as amplifier manufacturing or PA System installation to divert our attention away from repairing your equipment.  With our many years of education, experience and support from the top manufacturers, our service is second to none.  

Whether you have a 32 channel mixer that needs attention, a blown speaker that needs reconing, or you'd like to make modifications to your tube amp, we can take care of your needs quickly, reliably and economically at Uncle Sam's Jamms.
