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 .

"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"

Yes. I wish someone had told me I'd never be able to switch back to solid state. I've been trying and it's close to impossible. For me it's like the difference between a dry aged well marbled ribeye steak and the top round at a wedding reception.

In fairness to solid state I have a lot more to listen to. I'm sure it's out there somewhere.
