This amp is switchable between X Class AB, X SE Class A, X Aleph Class A just by adding or removing jumpers or more luxurious by the flick of a switch.

jumper setting
 
1,3,6,7 closed, 2,4,5,8 open => X AB

2,4,5,8, closed, 1,3,6,7 open => X Aleph

2,3,5,7 closed, 1,4,6,8 open => X SE Class A

Many other possibilities

e.g. swap JP 1,2,5,6 to 1N4148 then you get maybe some kind of old Aleph 0 (or was it A1?) system. Until a certain point SE class A then Aleph or so.

It's an English idiom meaning "when you've added almost everything you can think of adding." ;)
