unclej Posted July 20, 2006 Report Share Posted July 20, 2006 when i first decided to learn how to repair tube amps i bought an old superior instruments co. model tc-55 on ebay. over the last couple of years i've discovered some shortcomings..such as i couldn't test the el84/6bq5's out of the peavey bravo i've been working on. the spec sheet for the tester shows 6bq6 and 7 but not the 5 and i'm not knowledgeable enough yet to know if one of those settings will work on these tubes. anyway, i'd love some suggestions on another tester that will work on more tubes and won't break the bank completely. thanks Quote Link to comment Share on other sites More sharing options...
