Should your amplifier require servicehttp://www.radiodan.com/Henry/misc/Amp_service.htm
Henry Radio makes an effort to provide customer service on many items manufactured by them since the original 2K in 1963. However, many of the original parts suppliers used more than 30 years ago are no longer in business. Where possible, we have found alternative suppliers, but there are some parts that are simply not available any longer. Of course, all current models are fully supported.
If you find yourself requiring service for a Henry amplifier, the first step would be to contact the factory via e-mail, letter, telephone or fax. We can help you make the determination of what service might be required, and if the unit needs to be returned for factory service. Within reasonable time constraints, our technicians are available to offer advice on your service problem.
The majority of repairs on Henry tube amplifiers are handled in the field, with the advice of factory technicians and parts support from the factory. Most Henry tube amplifiers are heavy and difficult to pack and ship safely by the end user. It is to everybody’s benefit if the amplifier can be repaired without shipping.
