/34 & ba11-k regulator allocation?

[Jay West]

I'm picking different pieces of various leftover /34 systems to make mine. I 
have a question about the regulators in the back of the /34's ba11k.

Exactly what regulators are required as a minimum for a /34 that is just a 
dd11-pk with no expansion? Assume just a processor, one memory board, RL11 
controller, one DL11W... nothing heavy. I have one ba11 with regulators in 4 
positions and one with regulators in positions 1-3. However, one had a RK11D 
which I'm removing, one had a DD11-DK addition which I won't be using... and 
I would prefer to remove regulators that won't be used so they can sit on a 
shelf as spares and not be powered up all the time.

I've looked in the 11/34 user manual as well as the ba11k technical manual 
and I can't seem to put together this info. Can someone point me in the 
right direction?
