New Horn Tube Amplifier

This new combo amp in the works is for amplifying stringed instruments. The cabinet follows the construction details of both the Specimen Tube Amps and Horn Speaker bases. It also uses the engine turned sub-plates for convection cooling found on Specimen’s Octoblock and the slotted side panels that were first used on Specimen’s Fifty-watt Tube Amp. You could say it’s a clever combination of several Specimen innovations all rolled into one beautiful package.

This project stemmed from a request to revisit the original Horn Amp Combo I made about fifteen years ago. This model will use the splendid Eminence 8-inch guitar speaker rear-loaded with a vertical horn. The obvious follow up to this project will be a symmetrical pair of hi-fi mono blocks with a 6 1/2″ Fostex speaker.

All that’s left to do is apply the finish to the amp and horn, wire up the amp and machine the back panel. More pics soon!
