AVSL No longer Repairs THP Amplifiers.
Minor Technical Support is now left up to the various owners helping one another via the forum. Major problems with amplifiers can be fixed by most competent Ham Radio repair persons but Bill Grassa at http://www.n4ats.com/ is one of the few people that has extensive experience with THP amplifier repair. Bill will probably also repair older Products and
previously sold products bought direct from Japan. Almost all the parts in a THP amplifier are off the shelf components which can be bought from companies such as Digikey, Mouser and RF-Parts in the U.S. Some harder to find parts like meters and knobs can be directly purchased from Japanese suppliers listed in the parts list for each amplifier.
FOR MAJOR REPAIRS email Bill Grassa at: Grassa@earthlink.net
Phone: (407)-873-3070 (C)
Please DO NOT call Bill unless you have emailed him first about your situation and have gotten a reply from Bill.
