No, as a minimum you'll need to break the connections from the internal regulator to the main PCB or you'll destroy it & possibly damage your own PSU.
Many thanks-I have seen some professional PSUs which claim to require "only one connection" to be made etc-how are they connected?
Some PSUs (like the KAB) connect to the AC inputs on the PCB. This is the non-preferred method. You are better off removing the external regulator (clamped to the chassis) and connecting the 21V straight in. There is a thread with photos on how to do it here:

Remember that the optimal earth (0V) point is the lower-left post as you look at the PCB right way up.
Guys what transformer is used with the various alternative PSUs out there?
Toroid? EI? How many VA?
Hi Dimmy
Please would you pop over to the welcome section and introduce yourself before continuing? This is a basic requirement of membership. Thanks :)
I just did Martin. Sorry for the delay
I have just fitted my Long Dog Audio PSU supplied by David at MCRU.
The difference in the sound is remarkable. I am very happy....
There is only one thing that annoys me. The strobe is permanently on, so I either need to disable it, or connect up the switch.
If I connect he switch back in, what cable should I use. I have seen references to using a good quality cable, but a make and model, or even a link to what I need would be much appreciated.
I only need a single core DC cable, and I don't need much of it.
My thoughts were Teflon insulated silver cable. Would this be correct?
Just connect the strobe light through the now redundant power switch, Kevin. The type of wire is immaterial as it's just carrying the strobe DC.
