Since inheriting tubes in 1973, I check my tubes annually, before thanksgiving, ready for the holidays
My experience over many years:
1. stand in front of a monster tester at an electronic store checking everything from Fisher President II: fm tuner; am tuner; tape deck; two multiplex added; master control panel, two amps. legs, back and feet hurt, grumbling line behind me. maybe need 2 tubes in the whole lot.
2. wife got me a small portable tester of my own, wonderful. accurate? compared a few good and bad with the monster store unit, same results.
3. bought big jackson, had tech check the small one and it. they always agree.
4. stopped using the big jackson, use the small portable for myself and friends.
5. test new tubes when received, test annually, test when a problem occurs. found a few shorts; found a few weak; found a few ’unmatched’.
I recommend you and anyone who has tube equipment get a simple small portable tester. make sure the manual, real or download is available.
then, if you truly get serious, go for ’very good’. do real research and get one overhauled by a pro.
