A member of a range of amps made after the demise of Vox/JMI (late 1967). Once released from its contractual obligations to produce AC50s, AC100s and Vox's own line of PA amps, Triumph struck out with its own designs, reworking them for other companies - Vamp, Jennings (JEI), and Leo. They were also sold under the name "Johnson", Geoff Johnson being the founder-owner of Triumph.

The power section of the amp below was designed by Dave Roffey. The 100W version can be seen in the JEI V100 pictured on this page.
