Nr. | Description | Priority | Solution | |
---|---|---|---|---|
1 | Switches - use other pcbs footprint size and/or change panel to toggle switch | 1 | ||
2 | BOM : LOG for Volume LFO and VP out gain | 3 | fixed | |
3 | missing mounting holes for pcbs | 2 | open | |
4 | LED driver needed for gate led | 2 | fixed | |
5 | leds polarity on pcb | 3 | fixed ? | |
6 | LFO speed inverted pot, left is fast on the prototype | 1 | Or use reveresed Poti | fixed |
7 | panel holes too big for potis | 1 | open | |
8 | powersupply design not allowed - | 2 | open - use a own PSU - Yamaha PA30 and resctifier, capactitors | |
9 | markers for voltage test points missing | 3 | open | |
10 | more clearly infos about matched trannys and resistors | 3 | ||
11 | envelope change too CEM3310 or digital | 1 | open | |
12 | capacitors are too close next to the power supply section on mainboard | 1 | fixed | |
13 | use bigger traces | 1 | open | |
14 | Gate signal bleed in LFO | 1 | Blocker | fixed |
15 | V/oct unstable - waveforms wobbling - | 1 | Blocker | fixed |
16 | Lfo led not working | 3 | fixed | |
17 | Holes in vcf board and VCO board to mount on metal spacers - for better mounting | 2 | open | |
18 | Case doesn't fit with the panel | 1 | workaround possible | |
19 | ua726 | 1 | use normal matched pair trannys | |
20 | ssm2040 | 1 | use the new SSI 2040 !! | |
