Forget the tube tester. While I bought a Precision 10-12 off eBay back in the beginning (4 years ago) that works fine for, IIRC, less than $50, it's basically an emission tester type. Your DVOM can do the filaments. The times that I've replaced a tube that "tests" WEAK or REPLACE, it has made no difference in performance. Go figure! I still dutifully test every tube for fun, though. I just did a Philco 40-180 and it works great. To get to one electrolytic and another cap, the push button assembly nicely lifts out with all the wires and there's lots of room to work. P/M me with any questions.
