why buy new tubes? many, most last 10,000 hrs.
I just had my McIntosh mx110z tube tuner/preamp overhauled by Audio Classics. All 17 vintage tubes tested good, he left them all in.
You don’t know about the tubes that came in it right?
I advise tube users to buy a simple tube tester, which gives you knowledge, confidence, and, when trouble occurs, quickly find or rule out the tubes as the problems, as well as test what you buy, see how matched they are. My little tester always agrees with my big heavy one, I don’t bother with the big tester

You need to verify it has sockets for your tube types, and have the manual/chart/tube book to know the settings

don't let the rusty hinges scare you, they used poor quality metal to keep costs down.
