Default 813's

I have some 813 tubes from a friend that was getting rid of some of his ham gear. Think these will work in the tubelab SE? will it need a separate drive board or can I use the SE board as it comes and sub the appropriate values where needed? Was thinking of it PP but that would have to be two chassis, too much heat and weight. Thanks ps would like to also use 6sn7's and have some 866 mercury vapor, look cool but I heard they were hard to run and noisy

think using a separate variable power supply would work to drive the 813's? Maybe something from ebay?
