Re: '73 Marshall Super Lead head, value?
73 was the transitional year between Point to Point and the first 'simple tracer' circuit boards. 73 is the year that could be either of the two. If it's a point to point, it's worth between $1100 and $2000, depending on if the there's NO holes, mods, or chewed up tolex, or oxidized chassis and handle ends. If it's a circuit board 73, it's worth between $800 and $1300.
