Hints:
- For all Resistors, a metal film version 1/4 Watt should be used.
a.n.stands foras needed- The quantity for the combination of base board and extension board is reflected in the
Countcolumn. - In the
BaseorExtensioncolumns, the quantity for each board is reflected individually. - The capacitor values might be a bit different in the shopping carts (especially the 2.2uF). This is ok and due to lacking availability.
