Missing Parts - 47 ohm resistors
#4
5-6% change in value on that place, don't give 5-6% chance in filter, so 49,9 is just fine.
I don't remember exact, but I calculate a given value, perhaps 50 ohms, and then select the nearest common value, and it is/was 47 ohms.

It may seem random, but is not. Egon and I had a discussion long time ago if were to use BOTH 47 and 49.9 ohms since they were so close - the result was that the values ​​were just numbers on a shopping list, so we kept both values.

PCB12 ver2 had the two extra 2,2k resistors ... chance in design rom ver2 to ver3
