The best thing about cheap solid-state amps is that they make great donors for valve circuits. Mauro built his SE-5a Basic Kit into a Behringer Vintage GM110 combo. As with any donor amp build, Mauro started by checking whether the 257x67mm SE-5a turret board and transformers could fit, and that there was space for the controls.The next step is to drill and punch the chassis for the valve sockets and mounting points for other components. (Tip: check twice, drill once!)
