Hi Talkbass! I'm switching tubes in my Ampeg SVT Classic Amp, and since i'm far from expert in the area, the easiness from the Full Retube kits from Eurotubes appealed to me. More precisely one of 4 following kits; https://ssl.eurotubes.com/cart/index.php?page=view_products&category_id=213&sub_category_id=214 I've mostly been looking at the ''Ampeg SVT Classic & AV Standard Retube with KT88's'' option. (Im open to other suggestions, i'm only choosing what sounded best in the descriptions) My problem is that i live in Denmark, and the company is situated in USA. That means that i have to pay many different fees, which goes up to about 30% of the price + international shipping. I know that the guys from Eurotubes are experts, so i will easily trust them with my money, so i can get a full retube kit, but im a poor student, so im bound to find alternatives. My question is; Will i be able to buy equal tubes, in fx. the Thomann Web store? (The cheapest store in Europe) Thomann Cyberstore And if i buy them online, in separate packages, will the tubes still ''fit'' (paired, biased etc?) together? And will the tubes from Eurotubes and Thomann, be precisely equal? As i mentioned, i dont know anything about tubes, and i don't know if buying them seperatly will be the same, as buying them from Eurotubes. If so, will anybody do me the great favor of showing me what to buy on Thomann, precisely, so that the tubes will match the Ampeg SVT Classic & AV Standard Retube with KT88's kits contents. Maybe through some links, or a screenshot of a basket from thomann, containing the tubes. Hope you will understand my questions, you're welcome to ask me questions regarding further explanations. Thanks in advance! -Greatfull Kasper.
