Tube 6550 to test

aduri · 12th February 2009, 07:57 PM

I'd like to test this tube with my two tubetester I177 and BM215A Tesla but I can't find the card or the values to be set.

Can you help me please?

Bye
Antonio

If your tube tester has KT88 on the chart, test a known good 6550 on the KT88 settings, and use that value as your reference value for good/bad tubes. The 6550 is very similar to a KT88.
