J Burns fired this volley in news:l8g86u$vpe$1@dont- email.me:
IF he ran it, and not one of the local "service men". We had a LOT of "tube caddies" back then. Guys who carried a whole suitcase of tubes they bought mail-order, and just swapped new for old until they found (or didn't find) a problem. They couldn't actually _fix_ a TV if one latched onto their ass. Almost none of those guys owned any real instruments, and didn't have a clue that a CRT could often be "rejuvinated" for a period of time.
And, they knew nothing about cable routing, standoffs, or how to use baluns and co-ax (and yes, we had that stuff even in the days of ubiquitous twin-lead).
I owned half of a TV repair business in the 1960s. We fixed a lot of stuff the tube caddies left worse broke than when they found it.
So don't discount that running the twin-lead improperly couldn't have been done with a "professional".
