* | board: place and connect C450 | rekado | 2015-04-10 | 1 | -30/+39 |
| | |||||
* | place C450 on board, connected to external pin | rekado | 2015-04-10 | 1 | -10/+8 |
| | | | | | | C450 must be placed after pin CONN403 (BLEND) as it should be placed on the board and is not part of the off-board assembly (unlike the dual potentiometre mixing RETURN_HIGH and RETURN_LOW). | ||||
