Build Informations
Regular build, I use ceramic capacitors but you can use film/polyester.
When building modules, always do it in this order (from smallest component to highest):
- diodes
- resistors
- DIP chips
- capacitors (film/ceramic)
- Transistors
- Electrolytic capacitors
To solder the headers, place them and place both PCBs in their final position before fully soldering the pin headers/sockets.
For the next parts, always place them without soldering them on:
- jacks, pots and switches that go throught the front panel
Once placed, put the front panel in place, then fasten all components to it. Once this is done, you can solder all the remaining components.
