Without a specific goal in mind, it is a bit difficult to answer this one.
You would probably be better off with Google.
I got 16.900 hits.

i did google it and it mostly came with this forum theres not a lot of mods out there for this amp unfortunately

So what specifically do you want to accomplish?

Not knowing your experience with tube amp voltages, skill level or test equipment , I would recommend a pedal.
There are high voltages in the amp that can kill.
The DSL 401 amps that I have repaired sounded pretty good for what they are.
Marshall engineers did a good job on this amp.
You really do risk bitching up the amp by modding it.

Dual master is the amp with better results within a classical concept of the 900 series. Good for classic rock, punk, hardcore..
You may only need equip (good tubes) and good adjustment. In any case, this step is always prior to any attempt to modify.
