It seems to me that Marshall really got it right here – the right mix of hard wiring and PCB. The Valve sockets are all carefully hard wired to the circuit boards and the. Layout is very neat and as a valve bass amplifier I think this takes some beating really warm bubbly typical valve sound. Not sure when this one acquitred its leopard skin appearance but it sure isn’t original.
Standard valve amp problems of course are always present in the classic EL34 tube amp but don’t let that put you off venturing into valve amps. Think of it more as a tool that needs sharpening from time to time. Lifetime of these amps will easily go on indefinitely as all components are replaceable and readily available.
