1	BOM general comments.
2	a. Testpoints can be replaced by a short piece of wire. Under normal operations, only test points TP1, TP2, TP3 and TP4 are used for Common Mode adjustment.
3	b. Precision resistors can be replaced by other brands, but maintain value, size, tolerance and low TC.
4	c. For use of the small value compensation caps, see the Assembly Guide.

6	Update 1 Sep 2019: One builder noted that R15 and R24 were out of stock at Mouser. Alternative would be 4.7K (CMF554K7000BER6).
7		But in that case you should replace R10, R13 (original 20.8k) with 11.7K (CMF5511K700BEEB).
8		These resistor pairs are in parallel and the exact value should be as close as possible to 3.354k. Courtesy Dennis Miller, thanks Dennis!
