Hi there,

On some modules parts lists, there is no 1% or 5% does that mean they are just 5%?

And what wattage resistors should I use? or does it not matter?

Would it be worth getting better quality 1% resistors for the VCO module? Would this really improve the tracking?

thanks

In yusynth modules the default tolerance is 5% 1/4W unless specified otherwise. When 1% resistor are needed it is indicated on the schemo and the BOM.

In the VCO, only those resistors labelled 1% need to be 1%. Anyway you may use 1% resistors everywhere this won't impair the performance of the circuits.

Would using 1% resistors where not needed increase performance?

No it would not, the sensitive parts are those already specified 1%
