Lord Valve Speaketh:
I’ve seen ’em done both ways…I know a dude who’s been
running 6550s in his BF Super Reverb for more than 20
years, on the stock tranny. If you do decide to use
an auxilliary filament tranny, don’t bolt it down to
the chassis right away; run some long wires from it
around the back of the chassis, power it up while the
chassis is on the bench in front of you, turn it up
pretty loud, and experiment with moving the tranny
around so you can see what effect it has on the hum
level. Once you have it located in a place where you
get the least hum, draw lines around the feet with a
Sharpie marker and mark the holes. You may not be
able to put a bolt through all of the mounting feet
because of stuff located inside the chassis, but you
should try to mount it with all four if you possibly
can. Another way to go is to mount it to the wall of
the amp somewhere, and connect the wires with a Molex.
