I have different 41's:
Two of them have a yellowish LCD with lesser contrast and smaller digits: S/N 2227S, 2243S
The other three have sharp, crisp LCDs with digits, that are slightly bigger: 2209S, 2411S, 2505S
My first guess had been, that the older ones have an other LCD in them.
But the S/N seem not to support this (or one of them had it's LCD broken and replaced by the newer product)
Were there two different products in use?
Has anyone similar differences?
I read about the tantalum capacitor story, but I don't see how this applies here.
