72-73 Marshall Schematic

[gearhead]

Heh all, first post here!

Can anyone point me to a good 50 (or 100) watt 72-73 Ali Panel schematic?

It's the gainier/brighter sibling to the Plexi. Have hit a number of sites, but nothing so far (or maybe I'm just missing it?!)

Thanks!

you've already tried places like schematic heaven and the plexi palace?

[gearhead]

For schematics, yes. Schematic Heaven has a 1987, but the schemo was drawn in 1970.

Plexi Palace has schematics? I haven't posted there yet, but did some searches.

I dunno if they have them online, but I'm sure that somebody at plexi palace would have a metalface schematic.

try Dr.Tube also. If you're into Marshalls, I would buy a copy of The History of Marshall by Michael Doyle. It doesn't have everything but it's a good base. A lead amp from the period you describe would usually have a '69 type split cathode lead circuit with 100k feedback R, perhaps a linear taper for the volumes--not too different I would think (though nothing ever seemed to be set in stone with Marshalls--different parts brands, odd values, small variations, etc.).
