A few basic tube questions


For starting info i just purchased a pair of Quicksilver mid mono amps . These are my first tube amps i have owned .

Questions are : I plan on buying several sets of tubes for these amps by different manufacturers. When i have found the ones that i feel i like the best how do i sell the others that will have had an hours worth of use ?

Second question is in regards to the varients my amp can use . They are el34 , kt88,kt90 , and maybe a few more .Will all manufacturers of an el34 sound similar . Or might one el34 sound like someone elses kt 90 .

Third question is in regards to my new dodd preamp . That uses one tube of the 6 volt ilk . There are one of those as well in the quicksilver amps . Is it a good idea to use the same in the pre and amp ?

Lastly if anyone is interested in giving a quick (general description) on the differences of the el34 ,kt88 ,kt90 tubes .

A few more details. The amps were bought used . 8 years old to be specific. The boxes for the tubes came with the sale . written on them is a date of 08' . They are winged c tubes .A tesla e88c is the driver tube.and a mullard for the input tube. . My dodd preamp is new and the tube is some 8 buck cheapo . That uses one tube . I am going to buy a replacement for that first . Any benefit from using the same one as the driver tube on the quicksilvers ?
Also is there any info you wish you had when first starting out with tube gear you wish someone had told you that you later learned . Thanks
I am planning on using either Tubemonger or The tubestore . Or any of the top hits from a google search . Do i need to be leary of not getting what i am paying for or as these websites describe the tubes ? New condition is what i was planning . Is it wise to buy the small tubes that last alot longer used ?
I am running a pair of King Sound King electrostats. I was told by Gary Dodd whose preamp i bought that he just throws in a cheap russian tube because he expects owners will choose their own tube . I do not want to listen to that tube for very long.
The question regarding using the same tube driver tube in the amps as in the pre is my main concern right now . It is the same value in both the amp and pre . It seems like it would be a good idea to use the same manufacturer ?
