I still get em' today, do you?
Picture valves gone, sound valves gone, it's just a fuse or it wants a new resistor, I've heard that a time or two, and now the public has caught on...... the bulbs gone inside!
Another one for ya, many years ago I repaired a Sonab hi-fi, the speaker looks like a stool with the grill at the top, distorted and rattles on one channel the man said....... Not surprised, a dead mouse was wedged between the bass driver cone and it's casing. The chap said he thought he saw the cat chase something but wasn't sure, it'd entered via the bottom where the port opening is underneath.
