I've nearly finished building my Slow Loris, but realised that C9 is supposed to be a 1uF film cap, but I only have that in a electro cap. Would using one of them be ok or would it maybe cause some problems?
That is the output cap. It is perfectly OK to replace it with an electrolyt. Make sure to place
- towards Q1 (to the left in the schematic) and [-] towards output/volume pot (to the right in the schematic).
