Buy a used tube integrated with 2 output tubes per side that run push pull or ultrlinear for more power. See if you like it like playing with tubes etc. You should be able to find such an amp certainly a Jolida but get EL34s or larger. The other big brand (used) these days is Prima Luna. Peruse the integrated tube amps for sale. I saw many tempting items on another sites' trading section, but alas I mus rid myself of things not get more at the moment. Find what you want soon and really audition. If you buy well used you will get yor money back to try something else you might like better.
I can't give you much advice on SS for that money for twice that yes , so you will need some other Goner to help you there.
