* board: place and connect C450rekado2015-04-101-30/+39
|
* place C450 on board, connected to external pinrekado2015-04-101-10/+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).
* board: load updated netlist, remove pinrekado2015-04-051-31/+35

* simplify routing of melody return caprekado2012-12-311-35/+28
|
* redesignrekado2012-12-291-970/+1103
| | | | | | | - less space between resistors - removed trim pots - removed one signal buffer - routed Vcc through transistor pins (maybe change that later)
* bypass contacts are wired on the switch, off-boardrekado2012-12-291-14/+70
|
* remove melody buffer (preamp is buffered); remove trim potsrekado2012-12-292-94/+54
|
* correct namerekado2012-12-281-1/+1
|
* connect only one of the jack switchesrekado2012-12-282-22/+21
|
* reduce gain/distortionrekado2012-12-271-1/+1
| | | | | there still is some distortion which could possibly be eliminated by increasing the resistor some more.
* don't roll off low frequencies in bass preamprekado2012-12-271-1/+1

* put inputs on -Vcc when nothing is connectedrekado2012-12-271-3/+9
|
* improve coupling at mixerrekado2012-12-261-20/+66
|
* add coupling caps to return; remove from mixerrekado2012-12-261-148/+190
|
* update all coupling caps to 10uFrekado2012-12-264-18/+18
| | | | | this is to ensure that the voltage across the cap is low at all frequencies we care about.
