I thought so, so I got this from AI: Yes, there’s actually a surprising amount of truth to the old ritual of giving a vintage TV a good whack—what’s affectionately known as *percussive maintenance*.

In the era of vacuum tube televisions, several factors made this technique occasionally effective:

1. **Loose Connections**: Over time, the pins of vacuum tubes could indeed become slightly unseated due to thermal expansion and contraction, or just plain gravity and vibration. A sharp tap could temporarily re-establish contact.

2. **Aging Solder Joints and Components**: These TVs often had point-to-point wiring or early circuit boards with fragile solder joints. A knock could jostle a failing connection back into place—at least for a while.

3. **Dust and Debris**: Accumulated dust inside the cabinet could cause arcing or interfere with electrical contacts. A smack might dislodge some of that buildup, though this was more of a side effect than a reliable fix.

4. **Mechanical Switches and Tuners**: Channel selectors and other mechanical parts could develop poor contact due to oxidation or wear. A jolt might help them seat better temporarily.

Of course, this was never a proper repair.

Who here remembers taking the tubes out of the Tv down to the drugstore where they had a machine that tested them ?

Yes, I remember but they took them all away along with most of the drug stores

I preferred the term "impact adjustment"!
