I'm not specifically familiar with the EMC tester, but suspect it is a garden variety emissions tester.6550 setting will work fine for 6550A, the "A" has increased rating for plate dissipation.
ECC88 can be tested as 6DJ8 if that is listed.
The glow is typically a short light. Some tubes will test as having a short on some testers - but are still fine. I suspect when testing using buttons 4 and 5 on a 12AT7 your tester will falsely indicate a short.
