Marshall JMP 50wt schematic

[jubjub]

Hi people. Haven't checked in for a while as I've been crazy busy but could use some help yet again. I bought a 78 JMP 50 wt head that has been modded to include a pre-amp, but I want to return it to its original state. I've had a look but can't seem to find a schematic anywhere.
Any ideas?

Is this it?

If not.... it's probably here:

Take care,

Thanks

How good is that marshall site!

That marshall site is very good!  I gave up looking for a JMP1 schem years ago.  Now I can finally check out what's going on inside these things.  

Thank you Mr Snowberg.
