A B&K 747 is a good tester for the money. I beleive it's based on Hickock's expired patents. The good thing is that it's very easy to calibrate and does all the test you mention. The 707 is the tube version of this tester. These are on Ebay all the time.
Tube testers for 6922, 12ax7, etc, etc,
Looking for some advise with tube testers for 6922 and 12ax7 tubes. I'd like to buy one but don't have a clue as to which kind to buy, I see many types on ebay for resonable prices. I hear they need to be calbrated every so often. The concerne I have is buying one off ebay and getting some one's flea market special! I guess I'd like a tester that test for shorts, gases, mutual conductance, etc, etc. I would like to spend around $200 for a simple to use tester. Can this be done or am I spinning my wheels here and need to spend way more? Do any of you know a source for testers? Thanks in advance.
