Ron,
The description indicates you have some kind or MRI amplifier
("magnet type" is the tip off). Tokyo High Power's primary
business is MRI and industrial power amplifiers.
Tokyo High Power has a web site - www.thp.co.jp/top%20eng.html
and you may be able to find a "close" amateur amplifier in the
manuals section or try an e-mail to: info@thp.co.jp which is
given as a contact e-mail link.
