How much solder do people use? (Woodchips).
Today, very little, but in the '80s, I bought and resold well over 500 Grundig CTVs, mostly thyristor line types. To guarantee long term reliability (which I achieved), I used to de-solder and re-solder EVERY significant joint in the line scan stage. Boy did that consume solder. I regularly bought the 500g reels, until one day I saw the 2.5Kg reels giving a significant saving per gram. That lasted quite a while, but certainly not forever.
They also had numerous bad joints (mostly thro joints) in the Tuner/IF units, the self seek boards, and some RGB output boards. It was worth it, I asked high price and saw remarkable reliability.
Les.
Edit. I should add that I used a Weller gun. A semi-permanent calluss on my right thumb knuckle. That required a new bit about three week intervals.
