    The translations to standard type numbers is, of course, 
useful for any tester or just to know what the tubes are.
    I agree about the price of tube testers, they are 
ridiculous. I was very lucky to have obtained mine, 
including a decent TV-7 ages ago when they were cheap.
    Beside the TV-7 I have a good Weston tester that is more 
convenient because it will test multi-section tubes without 
resetting the selectors. However, it does not have a gas 
check. I also have a couple of other testers but they have 
problems. One is the kind that uses punch cards but I don't 
have many of the cards which limits its usefulness.
