Tube rolling is fun but can take many hours of trial and error and there are so many tubes out there and just because one brand works for you in a particular component doesn't mean it will be the perfect tube in another component. My amps use 16 tubes and my phono unit uses 22 tubes! Still I'd get the power cords set first so you then can hear tube differences easier.
Over the years I've gone from listening to 20 plus brands of ac cords and have finally settled on just 2 brands, what they are doesn't matter but finding the right ones for your system can bring a smile to your face every night.
