Silly Question - Which Input is Which? - I'm Easily Confused

[ThreeChordWonder]

Four input Marshall, like my JTM45 copy.

There's a "normal" pair and a "high treble pair", but which is supposed to be pair 1 and which is supposed to be pair 2?

Also, one of each pair is "high sensitivity" and one "low"? Which one is supposed to be the top one in each pair?

Thanks.

Hello ThreeChordWonder,

From the manual :

Thanks for that, it helped.

Leading on, can anyone post up a photo or a schematic showing the 68k resistors plus the 1 megs to ground, wired on the sockets, not the main board, so I could run shielded wires directly to the grids (pins 2 and 7 IIRC) on the V1 ECC83?

This is the Hiwatt scheme. Would it work on a Marshall?

Yes, they all follow the arrangement that Fender developed and everyone else has copied.

Here's a nicely detailed (though kinda lengthy) description of all the different combinations of this standard 4-jack arrangement, along with details of the interactions,etc.
