Resistors

All resistors are carbon film 5%. All are 1/4 watt unless stated otherwise. All suppliers listed have them so I'm not going to look up part numbers for each resistor on each supplier. Most parts companies have a minimum order amount so you can use resistors to pad an order from a particular supplier in case you fall short.
