I love my SICO (superior instruments co). It doesn't do what my b&k did but is much easier and quicker to use. All I need to test for is tube strenght and shorts. I'm not worried about matching for transconductance......
Lower End Tube Testers: which are worthwhile
Any help in this area would be appreciated. Of the lower cost decent testers (Hickok 533, 533a, 600, 600a, 6000, B&K 707, TV7) - which are the ones to hit and which are the ones to miss? I heard that the Hickok non "a" model's don't test 6922 family tubes - is that correct? Finally, anyone know anything about Stark testers? They were made by Hickok, or using Hickok designs. Thanks.
