Reviewed Mar 05th, 2015 by Simon Spiers

On a purley technical note this amp will more than likely need recapping in the power amp section. As it's direct coupled leaky caps may result in high dc offset at the speakers and intermitent protection activation. Main resivoir cap is a two section affair making replacment different.
Amplifier does sound good and is very well built. Also has pre out power in jacks.
A classic.
