Marshall 3005 Preamp

The Marshall 3005 Lead 12 was a mini-stack with a 12 watt solid state head made in England between 1988 and 1991. People claim it's a great amp and can get vintage Marshall sounds from it, and that it takes overdrives really well.



One note in the amp the preamp was powered by +16V/-16V so you'll want to build a bipolar power board.

Next, t Marshall Plexi 1987x.






With a switch to go between channels


With 2 separate inputs like the amp


With both channels jumpered



Note: I'm certain it will work, it's the same as the Sunn Model T preamp with modified component values, but will not mark it verified until someone builds it and verified the tone.
