You can invest in a tube tester also it might work out well if a group of audiophile friends go in on it together. A simple emmisions tester shouldn't cost all that much.
As for speakers that is always a matter of personal taste many love the vintage sound .
I own old (1959) JBLs and Klipsch La Scalas from the mid 1970s. I have to sell the Klipsch soon but will keep the JBLs. I also own Klipsch Heresy from 1976 which I hope to keep but I don't have enough space after a forced down sizing. Never mind my Focals and Von Schweickerts. OY!
