You should also get a potential divider for when working on the o/p area
as
you are bound to have the attenuator set on the wrong scale ,some time,
and
at least blow the first transistor.

You mean like a varible resistive dummy load for the output?


Another consideration for valve stuff especially, ie big kit, is the ability
to use the scope at the amp so being able to position it face up , floor
standing, is useful. A valvetester and also for personal safety a variac
plus isolation transformer and ELCB/RCCD/ GFCI
