preamps. One of the questions I have, other than general advisement

preamps are very low power devices ... consume milliamps ...
generally run a plate voltage of 100+ .. "wattage" is usually
used to describe the final output stage of the amp ...
even though a preamp tube consumes watts ( i*e ).

get another one specifically for the preamp?
You will need a power transformer .. for a power supply.
Instead of looking at entire tube amps .. you may want to seek out a
"tube preamp" only scematics / devices ...
FWIIW : I've seen tube preamp kits on ebay that may be more up your
alley ... do more home work ;-{
So is that Marshall schematic that I had an entire amp?
